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
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.
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
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.
