My 2005 SL500 is making a chirping sound when car is turned off and locked. The could continues when the car is driven and doors are locked. It originally started when the alarm system went off shortly after car was shut off and locked. This problem went away automatically and then the chirping began. Could it be a low charged battery problem, it reminds me of how a home smoke alarm chirps when the battery is low.

SOURCE: cannot disable anti theft alarm driving neighbours mad

There should be a relay under the hood for the security system, if you can not find it, try jacking the front of the car up, it should have a sensor that tells it that it is being towed and should turn off, unless of course it has a bad wire that is grounding out.

SOURCE: how do i disable alarm system????

under the rf floor board in the front you will see a false panel after removing carpet. remove false panel by loosening 10 mm plastic nuts your alarm module is 1 of the 2 modules on that false floor-it should have a 820 number in the part number-if it is not obvious call parts dept. and cross reference numbers-unplug module and you won't have worry about that annoying alarm anymore-hopefully i have been helpful

This is the problem due to your anti theft alarm system. You have not mentioned which brand of anti-theft alarm system you have? Anyhow, most of the systems have a reset switch inside the kit, open the kit and on the main board, u will find the reset button, press that and hold for 5 sec, the system will be reset. Otherwise, there are 2 or 3 fuses with the wiring of kit, remove those fuses and ur engine will wake up but the anti-theft system wont work then, hope this will solve the problem

How to stop beep when locking and unlocking camry le 2010

When Horn chirp is enabled, the vehicle horn will chirp on locking and unlocking the vehicle, to enable or disable the horn chirp:

1. Turn headlight switch "OFF"

2. Cycle the ignition switch from "LOCK" to "ON" three times (within 5 seconds) leaving it "ON"

3. The vehicle security indicator will illuminate continuously for 5 seconds

4. During the time the indicator is illuminated, operate the horn(for 1 second). The turn signals will flash once to confirm successful programming.

5. Turn ignition switch to "LOCK" and test system with the remote controls.

To disable horn chirp, repeat the procedure for enabling.

The user manual actually declares customizations of the smartkey must be done by the dealers using special equipment. However, the above procedure works on a variety of years and models. And I see no where in the user manual that refers to the horn and door lock even being a customizable setting.

I bought a new Keyless remote for a 2007 Forester from a Subaru Dealer to replace an original one that went bad after 2 years. I have followed the directions in the owner's manual to program it, but can't...

IMPREZA: 2005, 2006, 2007 and
FORESTER: 2005, 2006, 2007, 2008
Check for Immobilizer key on Forester XT models only.
information is always subject to change and correction imp05keylessremote1.jpg
new remote for 2005 Imprezas.
This is not the same remote as the 05 Legacy/Outback remote which also has truck/gate release on the front and a red panic button on the back.
Lock: press Lock button for 2 seconds or so to lock car, and arm optional security system. The car with chirp once and turn signals flash for locked, 5 short chirps and signal flashes if any door is not fully closed. The dome light goes on for 15 seconds and ignition key ring (if present) will light for 30 seconds when unlocked.
Unlock: press unlock one time for driver's door, press again within 5 seconds to unlock all doors inkling rear gate (wagon). The system does not open the trunk.
Panic mode: press and hold lock button for approx. 3-4 seconds to activate Panic mode. I panic model the horn honks and turn signals flash until either the lock or unlock button is pushed again.
Finder mode: Press lock button 3 times within 5 seconds to activate Vehicle Finder mode. The horn will honk once and the turn signals will flash 3 times
Distance: works within approx. 30 feet depending on battery strength, nearby concrete walls and etc.
Audible Chirp On-Off: the system will chirp when locked or unlocked. To turn OFF the chirps, unlock the door and then push both lock and unlock buttons at the exact same time for 2+ seconds. There will be 2 chirps indicating the the audible is off. To turn the chirp back on, repeat the process and the system will chirp one time when it is back on.
Battery: as the battery ages it will only work as you get closer to the car. When a battery is replaced, the transmitter must be re-synchronized with the Keyless control unit. To synchronize, press the lock or unlock button 6 times.
Programming: 4 codes may be programmed.
Sit in driver's seat and unlock all doors. Open and close the driver's door
Turn the ignition key from LOCK to ON position 10 times within 15 seconds. Be sure to stop at both lock and on. The horn will HONK once to indicate transmitter programming mode is activated. Leave key in LOCK position and don't remove it from ignition.
You now have 45 seconds to complete the programming as below.
Open and close driver's door again.
Push either lock or unlock button on the remote you want to program. The horn will honk 2 times when successful.
To continue and program other remotes at the same time: open and close the driver's door and push lock or unlock on the remote. The driver's door must be opened and closed between each remote you want to program.
Done programming? remove the key from the ignition and the horn will honk 3 times.
DELETE old codes? Reprogram 4 times, it will overwrite old codes.
Alarm Security System: optional on all models. When locked there is one chirp (can be turned off, see above), the turn signals will flash and the red 'security' light will start to flash once every 2 seconds except for STi which flashes twice every 2 seconds.
There will be 5 chirps if a door, hood, and trunk or gate is not fully closed
You can also arm the system by using the power lock button on the driver or passenger door as you get out of the car and then closing the door behind you.
Disarm the system: push unlock for 2 seconds
Lost remote, alarm activated? When you can't use a remote to turn off the system: open the door with a key or try to start the car and the horn will start to honk. Turn the key on-off 3 times within 5 seconds and the alarm will go off and you can start the car. It's simple!
VALET mode: To set valet mode or just to disable the security alarm system: 1. unlock all doors 2. physically open the driver's door 3. hold the UNLOCK button on remote for 2+ seconds. The red 'security' light will then flash 2 times a second until the car is turned on.
System has been Tripped (except for STi): if you unlock the door with the remote and it chirps the signal light flash 4 times, the system has been triggered;
Identification mode: To find out what happened and why the system was triggered:
Open and drivers door, leave it open. Turn ignition key from LOCK to ON 2 times and then leave in LOCK position.
Tripped code: 1 security light flash: a door has been opened, 3 flashes when the impact sensor was triggered, 4 flashes when the ignition was messed with or battery disconnected

Auto door locking on Ford Mondeo

It sounds like it has been deactivated so we are going to reactivate the auto lock.

The numbers I will be saying will have to do with getting this to work so:
you will need to put the key in to the ignition switch.

1= is back to listen to the radio
2= is to get key out
3= is just before you start
4= is for starting your car

When we do this 1 and 4 will not be used
Do this and we will hope that it works like it should:

1: Turn the ignition with you key up to on( don't start)

2: Press the power door lock control 3 times

3: now turn the key back once (to off position)

4: Press the power door unlock control 3 times

5: ok turn the ignition back up 1 time. (The horn should chirp)

6: Then press the unlock control, then press the lock control, again (horn will chirp 1's) If auto lock
was activated.

7: Turn the ignition back 1's, Then the horn should chirp once to confirm the procedure was completed.
