Hello everyone. I've got a 2003 Chry LHS which I have installed a DEI Valet 561R. I really like these units and have installed many of them. This Chrysler is giving me problems. It will start and run for about 3 seconds and die. I have rechecked all the wiring and everything is fine and working the way it's supposed to. The problem is, that I cannot verify the 555c anti-theft module as learning the keycodes. It's suppose to light the security light and give a confirmation tone, but this is not happening. I've witnessed it working properly on other Chryslers, but not this one. Could the module be bad or is there something else in this LHS that's keeping it from learning the codes. Thanks for you help.posted_image

Sorry, I forgot to mention that I also did the diagnostics and it comes up with a (+/-)shutdown.

I believe that the 555CW from DEI eventually will lose the codes to start the vehicle

I ususally just go with a 556U, you need an extra key, but it will work all the time
