So, all of a sudden, your key/remote is not working. So, let me paint a picture of what happened to me which inspired me to write this article for all you poor souls having the same issue. Well, it started when I was trying to go to my girlfriend's house. I had my stuff in the car, my kid in the car seat, and I turned the key, and it turned on! No problems there. 5 seconds later, it turned back off. Queue sad music. I tried it again, and again it turned on. yay! And again, it turned back off. Boo. Well, come to find out, the remote keyless entry had water damage, and it took me over an hour and a half to fix it. Well, I did what anyone would do, and I Googled it. None too helpful. So, that's why I'm writing this remote keyless entry troubleshooter lens.The reason your car shuts down after first starting is because your car is activating your SKIM security system which protects you from auto theft by rejecting key duplicates.
How to fix your Chrysler Remote Keyless Entry problems
Here's a quick step-by-step and some ideas that may help you.
Step 1: Open up the casing and change out the battery (CR 2032). This is similar to, if you were having problems with your computer, having to check your connections. This way is a much more affordable option than just replacing the key, as those can run you about $300.
Step 2: Find and use your other key.
Step 3: If changing the battery does not work, which it did not for me, then find your car battery, remove the positive and negative ends from their ports, and hold them together for two minutes. This should deactivate your SKIM security system.
After completing Step 1 and 3 I had my car up and running.
Step 4: Now I was reading a forum on how to resolder the motherboard, however I cannot find that forum now. If you find it or know of it please post it as a comment and I will link it later.
Step 5: If all else fails take your Remote Keyless Entry to a specialized locksmith for your particular car make. This may require some calling around and finding out who can repair your remote keyless entry. Or take it to the dealership and they will be able to get you a new one, but it won't be very quick they may need to order a new one. Both of these options are very expensive, as I mentioned before it can cost you a good chunk of change.
Well, that's all I have to say about that I hop you found it helpful and if you have more to add or something you think should be changed then please leave me a comment below.
