Hello,

Everyone I am new to the form. I have read through hundreds posts and I have not found an answer to the following problem. After installing a new Android head radio and a 4-channel amplifier and removing the old system original unit, my key fob stopped working. I was not able to lock and unlock my door after trying several different things, i.e., check, fees, batteries, PSE system short of reinstalling the original system I still cannot get the door to lock and unlock. Has anybody else ever had this problem?

Thank you for you response.

Wow that is great to know. Yes I did check the fuses associated with my CLS and other pertinent fues, all working.

One thing that I failed to mention I removed the Navigation and OEM Amp (everything) and I did not use the plug and play connectors. So nothing as far as the command unit, antenna(s) or CAN are not talking to my car.
