2003 GMC SIERRA 1500 HD I can enable the keyless entry remote but after three or four uses the system stops responding. changed the battery and checked fuses the locks still work with the inside switches and I have no other symptoms.

Hello Cathy

It does indeed have keyless entry. It needs reprogramming when you get a new remote. Also if you disconnect the battery. Usually a local car alarm fitting shop, or an auto-electrician will do it. Plus of course a Ford dealership.

The vehicle horns are activated under the following conditions:
?€¢
The horn switch is depressed.

?€¢
The body control module (BCM) commands the horns on. The BCM commands the horns on under either of the following conditions:

-
When the content theft deterrent system detects a vehicle intrusion. For further information, refer to Content Theft Deterrent (CTD) Description and Operation in Theft Deterrent.

-
When the panic button is depressed on the remote control door lock transmitter. For further information, refer to Keyless Entry System Description and Operation in Keyless Entry.

-
When the OnStar?® system is used to sound the horns, if equipped. For further information, refer to OnStar Description and Operation in Cellular Communications.

-
When the keyless entry system is used to lock the vehicle, a horn chirp may sound to notify the driver that the vehicle has been locked. The notification feature may be enabled or disabled through personalization. For further information, refer to Keyless Entry System Description and Operation in Keyless Entry

I only got hits back from eBay (& AMAZON)...
which would indicate this is a fairly ROBUST part...
(TYPICALLY: really popular parts = high failure rate).
((in my opinion))


No direct (part number) hits...!!

Hi.

To program ( or reprogram ) a keyless entry remote transmitter into the remote keyless entry module, perform the following steps:

1. Turn the key to ON or ACC and short the two terminals of the program connector, a two-pin connector located below the driver's side of the instrument panel at the base of the steering column. All doors should lock and then unlock.
2. Press any button on each keyless entry remote transmitter in turn. All doors should lock and then unlock. If the door locks do not respond, press the button again (up to three times maximum with the same keyless entry remote transmitter). If the door locks still fail to respond, go to Pinpoint Test A.
3. Repeat Step 2 to program additional keyless entry remote transmitters into the remote keyless entry module (up to four keyless entry remote transmitters maximum).
4. Turn key off.
5. Remove the short from the program connector. All doors should lock and then unlock.
6. Verify that the keyless entry remote transmitters have been successfully programmed by pressing the LOCK or UNLOCK button on each one, and observing that the system responds by locking and/or unlocking the doors.


I hope this helps you.

Thanks!

All pre 1995 GMC vehicles had to have an alarm system to have keyless entry... So, lift the hood and look for a red LED near the right front of the vehicle. If none - you don't have keyless... if yes, the you do.... and an alarm system too.

This link will take you to very good instructions try it worked for me www.wikihow/program-a-keyless-entry-for-a-chevy-silverado this works on GMC models also.

here's 2003 info:

• The doors do not lock/unlock using the remote transmitter

• Remote transmitter.
• Driver door module (DDM).
