P0513 Trouble code with no other problems

Question

Here is one I've never seen and am looking for some guidance. I have a 2007 Chrysler 300C I purchased 15 June 2013 and have had no problems since purchase. I had a local retailer install a Viper Model G5706V Remote Start-Alarm system on 7 March 2015. After 4 days I got the good old check engine light and my Diablo Sport Trinity tells I've got a P0513 - Incorrect Immobilizer Key error. I take it back to the retailer and they say they can't help me. Why? Because I have not had a single problem starting the car. It starts first time every time with both factory keys as well as remotely with both security remotes. No start and stall, etc. no problems except the Trouble Code on the ECM. I clear the code with my Trinity and it comes back in 1 to 3 days like clockwork. As it stands, I could care less with no loss of function but I live in a state that requires an inspection for registration renewal which I cannot pass with any trouble codes on the ECM. Has anybody seen this before or know how to get rid of this issue? Thanks for any help you can give me!

Answer 1

P0513 Invalid Skim Key

Chrysler does this when a remote starter alarm system is installed, What set this code P0513 are several causes  Incorrect VIN programmed into the PCM, No communication with SKEEM/WCM, Incorrect skim programmed in the PCM,Ignition key,Sentry key / wirelesscontrol module.This code condition also set a "U" code. Have the PCM reprogrammed
