I have purchased a PT Cruiser 2001 (UK) and the previous owner has lost the alarm fob. I have purchased a replacement. Is there any way to reprogram this myself?

I think you have reprogrammed, with a different code, one fob and not the others.
Take it to a Crysler Dealership for advice.

you can't bypass computer set software. You can however reprogram the key transponder and receiver. If you have NO working key, you need the dealership.

Disable anti-theft

Short answer, you can't!
Want to bypass your vehicle security system?
The short answer is you can't!

All modern cars have alarms and immobilizers. There is a chip in the key and a chip in the ignition lock. If both are present, the ECM (engine control module) releases power to the ignition circuit. When you turn the key, the starter spins the engine and you get a spark. If any one of those three items are not in the chain, you get the engine to turn, but no spark. There is no way to beat the system. You have to fix what is wrong, not find a way around it.


The immobilizer is in place to stop exactly what you are trying to do.

Jeremy: According to eHow.com: "

1 Press the "Unlock" key on your key fob to deactivate the alarm and unlock the car doors. If you've lost your key fob, unlocking the driver's side door with the key automatically deactivates the PT Cruiser's alarm.

2 Look for the black alarm box underneath the dashboard, on the driver's side of the car. Locate the override button on the box -- either a black or red button, depending on the year of the PT Cruiser -- but don't press it yet.

3 Put the key in the ignition and turn the key so that the battery is on, but the engine doesn't start. Quickly push and hold in the override button until you hear the alarm sound once, indicating the alarm is disabled.

If you don't have the Panic button then sorry, you can't program yourself, the dealer will have to program it to the RKE (Remote Keyless Entry) module in the vehicle, using their DRB scan tool.

As stated above, it is most likely your RKE (remote keyless entry module). It is easy to find and relatively easy to replace yourself. I just recently did so on my 2002 PT Cruiser. Got a used module from a 2005 at a salvage yard. Put in the module myself. However, you do have to take it to the dealer to reprogram so your remotes work with the module replacement. That cost me $50. If you are interested in doing the labor yourself, email me. [email protected]

battery of car is zapped of energy...not sure if alarm system to blame, after driving it for a few minutes..clock and radio display lights turn off, horn can barely be heard...sometimes, motor shuts down completely. have had to put in 2 new batteries in just a matter of 2 months?...any idea what this may be?

if the code was not put in the owners manual when origionally purchased, you can pull the radio and retrieve info from the back. provided to the dealer they can get you the code

Try unhooking the battery for about 10 mins. That should clear any problems and give the alarm time to reset.
