doors will not lock or unlock with key

[pgobeem]

I bought a 95 325is with 170000 miles on it. Cannot unlock or lock the doors with the key. The key will not turn either way only stays ar center. Car has an enforcer security system insalles. Could the alarm actuators be frozen not allowing the key to turn. It will lock fine if I hit either lock from inside the car, the trunk will lock and unlock fine with the key. Although their is not a master switch inside the car to lock or unlock the doors. any ideas would be appreciated
thanks

pgobeem, I have 97 328i with 158,000 miles and the same problem. Until now, I thought that my key is the problem because it's really worn out. I can't even get the trunk lock to engage. Though, when visiting mechanic once, he managed to engage trunk lock. I tried the same 30 min later and was not able. I haven't thought of alarm actuators, though.
My idea was to buy and install new alarm system with keyless. I'll keep you posted if I discover something new.

pgobeem, the problem may be with the programed chip in the key not matching the EWS system program and can only be handled by BMW

Change the battery in the keyfob first... You may have to follow your handbook procedure to reactivate it too... Try this first and get back to us...

the lock cylinder in the door may be stuck,, you might spray a lil WD-40 in there to see if you can get it to move,, and i dont think it needs the chip in the to open the door just the ignition

In this year 328 the doors lock and unlock with an elec motor thru the body electronics control module and fuse#35&7 supply the juice to the module. they are hot all the time

Still, it could be a worn/wrong key !

Does anyone know if key will work once alarm system is removed? Will car completely go into "manual" mode?

Theluis,

WD40 won't work. Tried it. Just makes a mess.

According to diagrams the other side of the lock is an electrical coil and harness which goes to the trans/ciever module the lock is mechanical only. Take off the inside panal and see whats what and if you have a side air bag remove the BATT ground first

You have to reactivate your system if you are trying to convert the automatic mode in to manual.

Made a big mistake by not reading your complaint earlier. Take the car to BMW something is frozen in the mechanical linkage that needs lubing and doing that thru the key hole can be very messy. sorry about my other advice. Also iif the key is worn they'll make you another

A really good lubricant to use on all locks and linkage is spray graphite, it is available in any Home Depot. I have seen where the key will not engage or turn, sprayed that and it freed it up. Especially during the winter months it is most important to keep all the locks in good working order.
