Review on ECCPP 2X Key Fob Replacement for 08-2012 Chrysler 300/Ram 1500 2500 3500 4500/ Town & Country/ Challenger/ Charger/ Durango/ Grand Caravan/ Magnum Keyless Entry Remote 05026196AD 05026347AD by Vangele Carson

Hands off. The locksmith programmed all FOB functions and worked for 2 weeks. There were fresh CR2032 batteries. Both stopped working the same day. To make matters worse, the original FOBs that came with the new car don't work. The locksmith who programmed the key fobs came back to fix the problem. It seems that the new FOBs messed up the car's electronics. Now a visit to the dealer (which I tried to avoid) is coming up in the near future.
