Hello just picked up my vrs today and I've got home and the unlock button has stopped working I can lock and do the boot but that's it. I can open the door with the key manually but when I turn the car on the alarm sounds for like half a second. Can any one advise me. Thanks

first things first, replace the battery. (in the fob, not the big one under the bonnet)

The other buttons work though?

Mine did a similar thing, then it didn't work at all so I changed the battery in the key and it works all good now
