On an '87, I seriously doubt it.  The standard antitheft system worked
with the onboard computer only when you entered a code for it.  It
didn't prevent the car from being entered.  It would only prevent it
from starting.  After 3 failed start attempts (using the key, but not
entering the code), it would sound the alarm horn for 30 seconds.

So am I.  These two events are either unrelated or purely fortuitous.

It's only a pain if they're related.  Generally, when the locks fail,
they simply fail to work electronically, so you need to operate them
manually.  They have nothing to do with the car starting or running.
You need to do a separate diagnostic for this.

I accidently locked the driver's side door and initiated the Central Locking
System.  Well, it took me a while to unlock the driver's side door again.
The passenger side is still locked and now the car won't start.  Question:
When the Central Locking System is engaged, will that shut down the entire
system, including starting the car?  I have at least the driver's side open,
but am surprised that the car won't start.  Secondly, what do I need to do to
disengage the whole system ... this is pain? Thanks for any response in
advance ... BMWFKK
