    Hello all.

    I have not been able to use my auto start feature because of a check engine light. Well its been taken care off, no more check engine light. I lock it and then I double press the auto start button it does two horn sounds and then it should start but it does not. Any ideas?

    I hear the two horn sound but wont auto start.

    Best.

    What is the trouble code? If you do not have a scanner, take it to Autozone for a free scan.

    How old is the keyfob battery? Have you tried your spare keyfob?

    If your battery is relatively new, you may have a problem with the keyless entry system that reads the key fob.

    No spare. Original fob broke. Got this one around 2 years ago and worked for auto start.

    Wait… why does your key fob for a Challenger have two buttons for a rear hatch?

    I have a 2010 SRT as well. My key fobs look like this:

    The previous owner probably lost the original key fobs and incorrectly bought a replacement designed for a Chrysler/Dodge SUV (i.e., for an Aspen, Journey or Nitro).

    You can buy two key fobs, designed for the Challenger, on E-Bay, for only $14.99. Then you can have them programmed by a locksmith.

    You have to many variables there, you will drive yourself crazy. Call a locksmith or someone who does e key programming. Maybe they will help over the phone.
