Hi guys, can anyone help me out on this one so i dont have to go to the dealers and get ripped off

The remote locking hasnt worked for months so its time it got sorted, i think the problem may lie in the override switch in the glove box which was turned off and i dont think its worked since then, is there a certain way it has to be reactivated?

Oh also ive put new batteries in the keyfobs today to eliminate that problem, i hope in doing so i havent eliminated the codes

Thanks Adam.
