How can I program my remote? - 2007 Buick LaCrosse CXL Sedan

It has to be programmed .
Remote Transmitter Programming NOTE: All remote transmitters are programmable and must be set at the same time.

1. Turn the key from OFF to RUN four times within three seconds, ending in RUN. The locks will then lock and unlock, confirming program mode has been entered.

1. Press any button on each remote transmitter to be programmed. The doors will lock and unlock to confirm that each remote transmitter has been programmed.

1. If additonal remote transmitters are to be programmed, repeat Step 3 within 7.5 seconds or steps 2 and 3 if more than 7.5 seconds have elapsed.

1. To exit program mode, turn the ignition to START or wait 7.5 seconds.

1. NOTE: Failure to wait at least 20 seconds will cause programming failures.
   Wait at least 20 seconds after turning the key to OFF or after the last remote transmitter has been programmed to activate a remote transmitter for testing or verification.

My experience with frequently-used vehicle remotes (any make) is this:
1. When relatively new or in good condition, if remote stops working, the button battery inside is dead or too low.

2. If battery is new, & remote still doesn't work, a solder joint on the circuit board inside may have come loose or broken.(You can try re-soldering using a low-heat pencil iron & thin RESIN-core solder -- even if you're not great at it, what do you have to lose?)

3. It's rather unusual for even an older, well-used remote to simply lose its programming.If this is the problem, it may be cheaper to buy a new after-market remote (or pair of remotes) that you can program yourself (only works with some brands & years of vehicles, so READ THE INSTRUCTIONS ON THEIR WEBSITE BEFORE BUYING AN AFTER-MARKET REMOTE), instead of going to the dealer for a normally HIGH-priced programming job.

4. Used OEM remotes that match yours exactly (check the part # of your remote & the used one you're considering) can often be purchased from a local auto wrecker (now called "auto recycler") for cheap ($5 to $10 is common), but will need programming.I always go thru the many they have, looking for one that appears new or like-new.

5. IF YOU MUST GET PROGRAMMING FROM A DEALER, usually it's the SAME PRICE whether you have 1 remote or several remotes/keys programmed at the same time.Since dealer programming is pricey, I always have 3-4 remotes and/or chip-keys programmed at the same time.(My dear wife loses chip-keys & remotes from time-to-time, so I keep a few spares on-hand.I've found inexpensive after-market chip-key blanks at some key cutters and/or auto parts stores, altho they still require programming after the copy is cut from yours.)

CAUTION:Some OEM anti-theft systems require that ALL remotes & chip-keys be programmed/re-programmed at the same time, whether they're original, used or new.Determine this IN ADVANCE, so you know what you're faced with.The good news is that for those vehicle manufacturers, dealers normally don't charge more to program/re-program multiple remotes and/or chip-keys, if all are being done AT THE SAME TIME.

6. If all else fails & you MUST buy a new OEM remote (which will require programming), try 2 things -- First, see if the dealer will make you a package deal on buying the remote (or 2 remotes, or a remote & a chip-key) AND doing the programming for a lower combined price.Second, it may be cheaper to buy a new OEM remote from a dealer who's had one in stock for a long time & wants to blow it out (or buy from online OEM seller) & then pay the normal programming price.See the CAUTION above.

There are lots of options here, so hopefully something is useful to you.

• You must have a programmed FOB to program another at home with my instructions below. If you don't have programmed one then you must get the first one programmed at the dealer.

1. Press LOCK button 5 times at 2 second intervals to re-synchronize remote.
2. Insert key into the ignition switch.
3. Turn ignition to the run (no start.)
4. Wait for ignition chimes to stop.
5. Using the working remote, press and hold the UNLOCK button on the remote for 4 to 10
6. seconds.
7. Within the specified 4 to 10 seconds, continue to hold the UNLOCK button and then press the PANIC button ( on the programmed remote ) for 1 second and release both buttons. A chime will sound to indicate that the remote programming mode has been entered ( allow 3 seconds for chime to sound ).
8. Within 30 seconds of the chime, press and release the LOCK and UNLOCK buttons simultaneously then press and release just the UNLOCK button on the same remote.
9. A chime will sound indicating the remote has been programmed. Press and release the LOCK and UNLOCK buttons simultaneously and then press the UNLOCK button on each new remote you wish to program at this time. Locks will cycle after each additional remote is programmed.
10. Turn the ignition OFF and remove key.
11. Try your remote.

• Hope this helps.

The great news is you can program your 2005 Honda Pilot Key Fob yourself. All you have to do is follow these instructions:

Most remotes can be self-programmed. If these procedures do not work, you must have your remote programmed by a professional automotive locksmith or dealership.

Procedure #1
Obtain all remote transmitters for this vehicle. Entering programming mode erases all remotes, so all remotes must be programmed during this procedure.

1. Turn ignition to ON (ll). (ON is the position just shy of starting the vehicle without cranking engine)
2. Press and hold the valet/disarm button located between the AM/FM and CD/TAPE button. The vehicle will respond by locking and unlocking the doors, indicating the vehicle is in programming mode. (You must continue to hold the valet button until instructed to release)
3. Within five seconds, press the LOCK or UNLOCK button on the remote. The vehicle will respond by locking and unlocking the doors, indicating the vehicle has programmed that remote.
4. Within ten seconds, Repeat step 3. for all additional remotes to be programmed.
5. Release valet/disarm button to exit programming mode. Test all remotes.

Procedure #2
Obtain all remote transmitters for this vehicle and read the instructions prior to programming.

Entering programming mode will erase all previously programmed remotes for this vehicle. You must have all remotes available for programming including working ones.

• Enter vehicle and close all doors

• Each of the following steps must be completed within five seconds of completing the previous step. If you take longer than five seconds or make a mistake, you must start the entire procedure over.

• Insert the key into the ignition, hold one remote in your left hand with additional remotes close by. We recommend taking remotes off the key ring to perform the procedure. When the instructions say to press the LOCK button, you should press the LOCK button on the remote for approximately one second then release it.

Perform each of the next three steps in order, then repeat all three steps two more times for a total of three times each.

1. Turn the ignition to the ON position, marked II.
2. Press the LOCK button on the remote.
3. Turn the ignition to the OFF position, marked I. (Do steps 1-3 three times)

Next, turn the ignition switch to ON position, marked II.
4. Using the same remote, press the LOCK button again. The door locks should cycle indicating the vehicle has ENTERED programming mode.
5. Using the same remote, press the LOCK button again. The door locks should cycle indicating the vehicle has PROGRAMMED that remote.
If you have other remotes to program then repeat step 5 with each additional remote one after another. Step 5 must be completed within ten seconds for each additional remote. You may program up to three remotes.
6. Turn the ignition to OFF. Test all remotes.
If your remote has a trunk button you will need to hold that button down for several seconds for that function to operate.

ATTENTION: You MUST HAVE one working remote to add one more to the system. If you do not have one working remote right now then these instructions will not work. You will have to have a Locksmith or dealership use a computer to program the first remote for you.


1. Turn ignition to the RUN position (as far as you can go without starting the engine).
Wait for chimes to stop.
2. Using original programmed remote, press and hold the UNLOCK button on the
remote for between 5 and 10 seconds.
3. While holding UNLOCK button, and before 10 seconds passes, press and release
the PANIC button. A chime will sound to indicate that the transmitter programming
mode has been entered.
4. Within 30 seconds of the chime, press a button on all remotes to be programmed
into the system including any previously programmed remotes, a chime will
sound after each remote has been programmed.
5. Turn the ignition OFF to exit the transmitter programming mode.

Thank you for using fixya and good luck

For most Ford vehicles you can self-program the remote for keyless entry. However there are some of the newer models that require professional equipment to program the keyless entry remote. You can check out what vehicles have self programming and which ones need professional programming here: https://www.keylessentryremotefob.com/Key-Fob-Programming-Instructions-s/1856.htm

In the meantime here are the most common Ford Keyless Entry Remote programming instructions:

*** THERE ARE 2 POSSIBLE PROGRAMMING PROCEDURES. ***Procedure #1Note: Obtain all remote transmitters for this vehicle.
Note: Do not depress the brake pedal during procedure.

1. Turn ignition from OFF to RUN 8 times within 10 seconds, with the 8th time ending in RUN. Door locks will cycle to confirm programming mode. (Off is the position where you can remove your key, RUN is the position just shy of starting your car.)
2. Within 20 seconds press any button on the first keyless remote to be programmed. Door locks will cycle to confirm programming. If you only have one remote then skip to step 4.
3. Within 20 seconds, press any button on the second keyless remote. Door locks will cycle again to confirm programming. Repeat step 3. For all other remotes.
4. Turn ignition to OFF. Locks will again cycle to indicate end of programming mode.
   
   Procedure #2Note: Obtain all remote transmitters for this vehicle.
5. Fasten seat belts and close all doors.
6. Turn ignition from OFF to RUN 4 times within 6 seconds, with the 4th time ending in RUN. (Off is the position where you can remove your key, RUN is the position just shy of starting your car.)
7. Turn ignition to OFF. Acoustic signal will sound and system warning lamp will illuminate to confirm programming mode.
8. Within 10 seconds, press and hold any button on the first keyless remote. Wait for acoustic sound and warning lamp to flash (confirming programming) then release button on remote. Wait 2 seconds but within 10 seconds repeat step 4. For all other remotes. If you only have one remote then continue to step 5.
9. Turn ignition to Crank or wait 10 seconds to end programming mode.

try to reprogram the remotes using these instructions..........
i assume for 02 explorer not th 05 frestyle listed (although similar procedure)
Remote Transmitter Programming NOTE: All remote transmitters are programmable and must be set at the same time.

1. Make sure that the anti-theft system is not armed or triggered and key code programming is not active.

1. Open the door, then press the driver door lock control switch UNLOCK button.

1. Turn the key from OFF to ON 8 times within 10 seconds, with the eighth turn ending in ON. If the program mode is sucessfully entered the doors will lock and unlock to confirm.

1. Press any button on a remote transmitter, and the doors will lock and then unlock all doors to confirm that the remote transmitter is programmed. All remote transmitters must be programmed within 20 seconds of each other. Up to four remote transmitters can be programmed to the vehicles security module each time programming mode is entered.

1. If the door locks do not respond for any remote transmitter, wait several seconds and press the button again. If the door locks still fail to respond, refer to Locks, Latches and Entry Systems — Late Build or Locks, Latches and Entry Systems — Early Build in this section.

1. NOTE: Exiting is acknowledged by locking and unlocking the doors if at least one remote transmitter has been programmed.
   Exiting the programming mode is accomplished if one of the following has occurred:
   • The key transitions to OFF.
   • 20 seconds have passed since entering programming mode or since the last remote transmitter was programmed.
   • Four remote transmitters have been programmed.

Is this the procedure u are using? this is from the factory manual.

ATTENTION: You MUST HAVE one working remote to add one more to the system. If you do not have one working remote right now then these instructions will not work. You will have to have a Locksmith or dealership use a computer to program the first remote for you.

1. Turn ignition to the RUN position (as far as you can go without starting the engine).
Wait for chimes to stop.
2. Using original programmed remote, press and hold the UNLOCK button on the
remote for between 5 and 10 seconds.
3. While holding UNLOCK button, and before 10 seconds passes, press and release

mode has been entered.
4. Within 30 seconds of the chime, press a button on all remotes to be programmed
into the system including any previously programmed remotes, a chime will
sound after each remote has been programmed.
5. Turn the ignition OFF to exit the transmitter programming mode.

6. Test Remotes

Hi, Stacie,

here's the instructions for a 97 TL - I hope they're the same.

Note:
Entering the programming mode cancels all learned keyless remotes, so
none of the previously programmed remotes will work. You must reprogram
all of the keyless remotes once you are in the programming mode.
You must complete each step within 4 seconds of the previous step to keep
the system from exiting the programming mode. You must program remotes
within 10 seconds of each other
1. Turn ignition switch to ON (II)
2. Within 4 seconds press the LOCK or UNOCK button on one of the remotes.
(An unprogrammed remote can be used for this step.)
3. Within 4 seconds turn ignition switch to LOCK (0) position
4. Within 4 seconds turn the ignition switch to ON (II)
5. Repeat steps 2, 3 and 4 two more times using the same keyless remote
used in step 2
6. Within 4 seconds press the LOCK or UNLOCK button on the same remote.
Make sure the power door locks cycle to confirm you are in programming
mode.
7. Within 10 seconds press the LOCK or UNLOCK button on same remote.

8. Within 10 seconds press the LOCK or UNLOCK button on all other
remotes you want to program. Make sure door locks cycle after you push
each remote button to confirm system has accepted the remote.
9. Turn the igniton switch to LOCK (0) to exit programming mode.
10. Test remote(s)

Hope this helps :)
