01 PT Cruiser Keyless Entry Problem

I replaced the batteries with no change. (I figured the chance of having two
different fobs go dead on the same day was zero, but someone insisted.) The
dealer quoted me $37.50 to reprogram the car. It took 15 seconds, and he let
me go at no charge, so life is good again. They don't know why they
deprogram either. Ain't computers wonderful!

...

Change the batteries and let us know if anything changes. - RM

Congratulations! We're ALL right, one way or another!

I would assume that powerful magnets or motors might be
capable of deprogramming a FOB. Has anyone had that experience? - RM

Sorry for the late response. Hopefully this will help someone else. From my experience, the receiver may have a relay that gets 'stuck' while power is present. What I did was inspect all the fuses located in the fuse box under the hood and just behind the air filter housing. I wish I could tell you which fuse it is but it does have constant power (i.e., radio). It would be wise to start there, but if that is not it just remove and reinsert the fuses. I hope this helps someone who is about to spend a lot of money with a mechanic who may/may not just replace the receiver $$$. Good luck!

And if that doesn't work, the dealer should reprogram them to work with
your car for free.

Why for free?

Are they expected to be a non-profit organization?

...

I believe that Marty sees that an 01 is still under warranty,
including FOBs - it's worth asking! - RM

Why not just do as the manual says to when programming new Key Fobs? I've
done the procedure in my PT, according to the directions in the manual, to
try to get a third Fob working from another car. The car even gives audible
feedback when it hears a new, valid Fob. Unfortunately, the third one I had
was intended for an Intrepid, and thus wouldn't work.

My point is - why ask the dealer to do something that your own manual can
guide you through in less than 60 seconds?

...

Ok, I was a little off of your meaning. But the assumption the OP was
going on is that the FOB had malfunctioned, BUT he/she also assumed
that the dealer could fix it. Maybe, following your suggestion, it
could be fixed by the operator (unless he swapped with the wife's
intrepid FOB!) - RM
