Jeep SRT 2012 Keyless Go not working

Hi

Need a Jeep specialist on this one.

I have a Jeep SRT 2012 in the shop. The panel shop took the front door off to paint it. After they put it back together the keyless touch on the drivers door handle and the start/stop button does not work. It starts with the key in the ignition.

We did this 6 months ago and the tradesman that worked for us rang his mate at jeep and got it going. I didn't write down the procedure.

Could I get the procedure on recalibrating the key-less go again?

Thanks

Buck
