I know this question is old but I recently encountered a similar problem with my 1995 323 BA and this may help someone else. Override the immobilizer by doing the following:


open the car via the drivers door
put the key in the ignition
turn the key to ACC
now turn the key to ON
repeat the last 2 steps X 12 quickly (ignore the indicators flashing and the central locking activating).
the dashboard should be lighting up as normal.
Now turn the key to START

The RCDLR (remote control door lock receiver) could have failed, or the battery in your key fob is dead. The only way to get the immobilizer off is to use the key fob.

put key in door lock,unlock/hold key over windows will go down....then lock/hold key over,windows will go up,press and hold unlock button on remote for 30 secs,you have just reset the alarm/immobiliser.

I have the same problem kinda. Lost my master key and sent my ecu off with a home made 2 button key to program immobiliser. This key works to start the engin and drive but I cannot get the key to program with the alarm and locking system. You can try the following steps as may work for you.

I can get my car into programming mode after step 1 but step 2 does not work for me. The locks do not go off at all, not once or twice. Battery in remote key is fine as LCD lights red.

Can anyone help please?
