Re: WK2 push to start/ keyless entry not working
Your symptoms relate exactly to an issue I had with ours when installing extra wiring to the tow bar.
I had removed the plastic trim and attempted to start the car, with the result damaged key message. Once i reinstalled the wiring the car started keyless again no worries.
This from memory as it was nearly 18 months ago now......
The antenna is clipped to the underside of the plastic surround across the tailgate, if you look on the underside there will be a receptacle for it. To remove the plastic trim you have to disconnect the antenna wiring. As I recall the antenna was about 1/2 inch square and about 3 inches long, black, with wires to a plug in connector.
If you are lucky, the antenna is still there and just needs to be reconnected. If not you'll need a tailgate TIPM antenna.
The vehicle did store a code relating to the fault as my dealer questioned me whether I had had a key issue at my next visit.
Hope it can easily be sorted.
