Remote locks but won't unlock help.

![Default](https://ls1tech.com/forums/images/icons/icon1.gif)
Did a search and found a couple of things that I tried but that didn't solve the problem.
Basically, I have a 97 Trans Am. The remote locks the doors but will not unlock them. This is a huge PITA b/c I have to get in the car like I'm freaking Flash Gordon to make sure the alarm doesn't start going off.
I know it's not the battery, since the doors lock just fine. I also tried holding the lock and unlock buttons for 7 seconds, and that didn't help.
Any ideas or helpful insight is greatly appreciated.

I had the same problem where the keyfob would lock but not unlock. I bought a brand new one off eBay and programmed it myself (takes a whole 15-seconds) and haven't had an issue since.

How do you go about programming the one you get off ebay? I may try that. But I will hold off on it to see if anyone else has any other solutions to this problem (especially since buying a new fob only worked in one instance but not the other).

Ok guys, here you go, if there are any problems or something doesn't work right let me know and I'll change it.
'94 Programming
1. Keyless entry receiver can be programed to receive Vehicle Access Code (VAC) from any 2 random transmitters. To program a keyless entry module receiver, connect a jumper wire between terminals "G" and "A". Receiver will cycle door lock actuators within 1-3 seconds to acknowledge that receiver is in program mode.
2. Press any button on transmitter once. In response , receiver will will cycle door lock actuators to acknowledge that the transmission has been received. Press any button of second transmitter once. In response , receiver will cycle door lock actuators to acknowledge a transmission has been received. Remove jumper from DLC and verify system operation using all transmitters.

To program a keyless entry module receiver, connect a jumper wire between Data Link Connector (DLC) terminals No.4 and 8 (16-pin DLC) or terminals "A" and "G" (12-pin DLC). Receiver will cycle door lock actuators within 1-3 seconds to acknowledge that receiver is is program mode.
2. Press any button on transmitter once. In response , receiver will will cycle door lock actuators to acknowledge that the transmission has been received. Press any button of second transmitter once. In response , receiver will cycle door lock actuators to acknowledge a transmission has been received.

Programming
1. Turn ignition off. Remove RADIO (fuse No.17) from fuse block. Cycle ignition switch from OFF to RUN positions 3 times within 5 seconds until door locks and hatch release cycles, indicating Body Control Module (BCM) is in programming mode. Leave ignition switch in RUN position.
2. Press both LOCK and UNLOCK buttons on remote control door lock transmitter for 16seoncds. Door locks will cycle once, confirming transmitter code is programmed. Door locks must cycle completely to unlock before proceeding. Any transmitter code that was previously programmed has been erased. BCM is now programmed to remote control door lock transmitter.
3. When programming BCM to match remote control door lock transmitters, first transmitters code matched will be stored in memory unless a second remote control door lock transmitter is matched at the same time. If programming BCM to match a second remote control door lock transmitter, repeat step 2). This must be done before RADIO (fuse No. 17) is reinstalled. Turn ignition off. Reinstall RADIO (fuse No. 17) to fuse block.
NOTE: Always program both remote control door lock transmitters when replacing a lost or damaged transmitter.

Entering Programming Mode:
1. Turn ignition switch to RUN position to disarm content theft deterrent system.
2. Turn ignition switch to OFF position. Remove RADIO (fuse No. 17) in instrument panel fuse block.
3. Turn ignition switch to ACC position.
Feature customization changes may now be made.
Exiting Programming Mode
To exit programming mode, turn ignition to OFF position and install RADIO fuse.
LAST DOOR CLOSED LOCKING & LOCKOUT PREVENTION:
1. Enter programming mode. See BCM PROGRAMMING MODE.
2. Press LOCK switch on door. Count number of chimes. Number of chimes is current mode vehicle is set for.
3. Press LOCK switch on door again until number chimes heard corresponds to desired mode See LAST DOOR CLOSED LCOKING & LOCKOUT PREVENTION table.

REMOTE TRANSMITTER
CAUTION: If vehicle is equipped with radio anti-theft feature (THEFTLOCK(R)), obtain secret code from customer. Disable THEFTLOCK(R) prior to disconnecting power to vehicle or removing RADIO fuse. See RADIO ANTI-THEFT FEATURE (THEFTLOCK(R)) DISABLING.
NOTE: Programming of remote transmitters cannot be done simultaneously. First remote transmitter must be programmed completely before programming next remote transmitter(s). A maximum of 4 remote transmitters may be programmed into Body Control Module (BCM) memory.
1. Turn ignition switch to RUN position to deactivate Content Theft Deterrent (CTD) alarm system (if equipped). Turn ignition switch to OFF position. Remove RADIO fuse No. 17 (15-amp) from instrument panel fuse block. RADIO fuse is located in lower right-hand corner of fuse block.
NOTE: While programming remote transmitters, wait for doors to unlock. Failure to do this, will cancel programming.
2. Cycle ignition switch from OFF to RUN position 3 times within 5 seconds, leaving ignition switch in RUN position. BCM will indicate programming sequence is active by activating hatch release, locking doors, then unlocking doors.
3. Press and hold both LOCK and UNLOCK buttons on remote transmitter to be programmed for 15 seconds. Doors will lock and unlock, and hatch release will activate to verify remote transmitter has been recognized by BCM.
4. Repeat step 3 for remaining remote transmitters. After programming remote transmitter(s), reinstall RADIO fuse. Turn ignition switch to OFF position. Enable THEFTLOCK(R) (if equipped). See RADIO ANTI-THEFT FEATURE (THEFTLOCK(R) UNLOCKING.

StangMan: Thanks a lot, I will give this a try. If I understand this correctly, under the 96-00 programming step I am to hold the lock and unlock buttons for 16sec simultaneously, correct? (that's similar to what I had found in my thread search but I didn't know to take out the fuse and to cycle the car from on to off 3 times). Will report back with results.
