My 1996 318i 2 button remote key fob stopped working. Even with a new battery the remotes led is in a constant dim on state without either button being pushed (the battery will go dead several hours later)

I picked up an identical remote (same fcc#/part#) off ebay and the remotes led status is showing proper operation however I am unable to get it programmed as per the instructions I believe to be correct that I posted below.

As per the instructions below I am not getting into the programming mode after 5 ignition cycles with the trunk open (no chirp or security light on).

Questions:

1) Am I using the correct programming procedure?

2) After 5 ignition on/off cycles do I end with ignition on or off? (i tried it both ways)

3)) Is it possible the security system isnt recognizing the trunk open thus not going into the programming mode.? Any easy way to check?


Thank you for your help!!!, Ken

Programming mode I tried.
for the 2 BUTTON REMOTES
Initializing Transmitters:

Each remote transmitter has a unique identification (ID) code. In order for the replacement alarm module to recognize the transmitters, you must follow the procedures detailed below exactly , so that the module learns the ID code of each transmitter.

This code-learning (initialization) procedure must be followed precisely, within the sequence and time limits specified, for the procedure to be carried out successfully.

A. Preparation:

1. Close all doors, trunk, and hood.

2. The security system must be in the "disarmed" condition. The key must be removed from the ignition switch.

B. Entering Code-Learning Mode:

1. Open the trunk and leave it opened.

2. Open the driver's door and sit in the driver's seat.

3. Close the driver's door.

4. Cycle the ignition switch five times between the "OFF' position and position 2 (Ignition "ON"). The red LED will illuminate continuously, and the siren will "chirp" once, to indicate that the code-learning mode has been initiated.

Do not start the engine.

The ignition switch cycling in Step B4 must be performed within 10 seconds.

The sequence in Steps B1 through B4 must be performed within 45 seconds.

C. Register Codes:

1. Open the driver's door and remain seated in the driver's seat.

2. Close the driver's door.

3. Press and release any button on the remote that you want to register into the module. The status LED will shut off momentarily to indicate that one ID code has been registered.

4. Repeat Steps C1 through C3 to register any additional ID codes.

D. Exiting Code-Learning Mode:

1. Open the driver's door and exit the vehicle, leaving the door open.

2. Close the trunk.

3. Close the driver's door. The LED will turn off and the siren will "chirp" twice.

4. The initialization procedure is now completed. Test all remote transmitters to confirm operation.

Im pretty sure it was a factory option on this vehicle, the remote is a official BMW remote.

When I repaired the ignition cylinder and I lost the "key sence" operation (reminds you the key was left in the ignition). Perhaps the "key sence" is required for the remote programming?

When the old remote worked (it stopped working after I locked the doors and set the alarm). I was able to silence the alarm by cycling the ignition switch.

I had the keyless entry security module out (located behind the glove box). There were no external switches or openings on the unit.. I opened it up (four philips screws) and tried altering the two dip switches in all possible combinations and didnt get any visible (LED by lighter) or audible response.

I manually operated the key sence switch in the
ignition switch in conjunction with above procedure and I still had no luck.

After two hours I gave up and walked away.

I went out to the garage a hour later to give it one last try and I got into the programming (led on/ chirp)!!!!! I cant help but wonder if the security system didnt recogonize my trunk/ door switch operation the first 20 attempts.

The programming instructions I posted above were correct (the trunk open driver door operation and five on off cycles) and I was able to sucessfully register my Ebay procured remote keyless entry key fob.

Thank You all for the suggestions,
Ken

Maybe because you had the module out and then plugged it back in it may have reset its self, at least you got a result.

I usually don't recommend this but this seems like an unusual problem with the alarm system that requires some professional assistance. If it's a true BMW alarm, you should take it to the dealer and get it reset or whatever needs done. It shouldn't cost too much and you can have piece of mind that the work was preformed by a specialist.
