Door Locks oscillate up and down when brake is app

[Big E]

I have an intermittent issue with my door locks on my 01 PT, sometimes and with no particular timing the door lock will oscillate up and down when I apply the brakes, this gets to be a real problem in traffic because each time I apply pressure to the brake pedal the locks jump open/close/open/close until the brake pedal is released. I'm thinking the problem may involve the keyless entry module, only because it seems to be the only link between brake lights and door locks.

Help!!!

Welcome to the forums.
Nasty problem - and intermittent, too - that means if you fix it, you're never really sure, because it may just be not happening that time....
Hate to say go to dealer, but they should know the car best.[:I]

Welcome Big E. I haven't heard of the problem before, but it sounds like you're on the right track. Try this link ptdoityourself.net there may be someone there that has had the same problem. Good luck and good Cruzin.

There have been several with the RKEM replaced. That has always cured it.

MX-5; Thanks for the info, is this a do it yourself replacement? Also do you know how to access the RKEM so that I can unplug it to verify the problem stops

Thanks

Only a DRB-III scanner can program the transmitter codes and VIN number.
Leave it to the dealership.
