Hey I’ve been getting “Keyless Error Access” since yesterday.

I cant go to a mechanic it’s holiday here at the moment, anything i could do? I tried playing with the key, turning car off and on.

I also had a pdr the previous day on the right door.

Anything i could try,it wont stop pinging while driving.

Could it be a "key" battery low or out of range / shielded in some way?
