2001 BMW 325I DOOR ENTRY

I would swap Door lock relays with power window relays to see if they work.

It's unkiely that all the door actuators are bad. The problem sounds like a voltage loss to the circuit. Check the fuses for the door locks.

You did it like this ?
Programming -Keyless Entry Remote Transmitter NOTE: All keyless entry remote transmitters (15K601) must be programmed at the same time.
NOTE: All previous transmitter identification codes (TIC's) will be erased when programming mode is entered.
NOTE: To program (or reprogram) the keyless entry remote transmitters into the generic electronic module (GEM)(14B204), perform the following steps.

1. Turn the ignition from OFF to RUN eight times within 10 seconds, ending in RUN. If the GEM has successfully entered program mode, it will lock and unlock all the doors.

1. NOTE: The first TIC must be entered within 7.5 seconds of entering the program mode and additional TICs must be entered within 7.5 seconds of the first TIC. The programming mode is exited whenever the timing constraints are not met. Press any button on a keyless entry remote transmitter, and the doors will lock and then unlock to confirm that each keyless entry remote transmitter has been programmed.

1. If the door locks do not respond for any keyless entry remote transmitter, wait for several seconds and press the button again.

1. Turn the ignition switch to the OFF position, or wait up to five minutes after step 1, to exit program mode. If a keyless entry remote transmitter has been programmed (or reprogrammed), the GEM will lock and unlock all the doors one last time.

1) Get in and close all doors.
2) Turn on the ingition and turn off quickly. (No more than 5 seconds) to start the process. Next action must take place within 30 seconds.
3) Remove the 1st key.
4) Hold the key up near your left shoulder (this is so it is closer to the remote reciever antenna - someone else suggested this).
5) Hold down the unlock button (which is button 1 on my key) and press the lock button 3 times (center button on my key). Release the unlock button and the doors lock which confirms the operation.
6) Quickly repeat steps 4 & 5 for key #2 etc.
If it does not work, try doing the keys in opposite order. Key 2 then key1, vs 1 then 2

I had same problem. Driver door would lock/unlock with key in keyhole in door, but not with fob, and other doors would not lock/unlock. Even once inside none of the doors would lock/unlock with lock switch, or even by pulling handles. Mechanic (very trustworthy) explained I needed a new control module (cost me $600). Good Luck. $600 is better than having to roll down the windows so Grandma can Luke Duke it outta the car.

The connector on the rear lights gets burnt and you have to replace the connector, the burnt wire, and the taillight assembly. For the locks it could be a few things. Does the central lock button work all the doors? Does the remote function work with any doors, or trunk? Could be anything from the driver's door lock actuator to the general module for the car. If you have a scanner to check the ZKE module and code "general locking, unlocking relay" is there then a new general module is needed. The relays are built into it.

try pressing the keyless entry unlock button twice

insert the key into the drivers side or passender side front door, twist the key and pull open on the handle at the same time and the door will open. It might take a few times to get it, but this does work, source BMW AG Munich.

check the fuse. if the remote only does not work, the remote needs recharged by the ignition. if its the locks its probably a fuse. check your manual for fusebox location

if you have a bmw 325i 2001 model try this solution:
if you have one key , go on to the next step. if you have more than one key, like two or more than follow this procedure.

step one: unlock the doors with your key and get in and close the doors but do not lock them
step two: put your key into the ignition and turn it but not to start the engine, do this less than 5 seconds

step three: take the key out of the ignition and put it near the shifter. press and hold the unlock button while pressing the lock button 3 times. you have 30 seconds to do this. the doors should lock and unlock automatically signalling that it the key has been reprogrammed. if you have more than one key follow those steps for each one except for step one. remmember you have only 30 seconds for each key. that should help you.
