There is a good chance it is the receiver for the remote. Try unlocking with the key then locking and unlocking with the remote without opening the door.

If that works the receiver is timing out and going to sleep.

It could be the drivers door lock control unit or the BCU playing up. Alternatively it could be your main battery is low on power. If you get really stuck and locked out don't do what I did and break a side window but crawl under the truck and connect onto the starter motor with a battery charger or slave battery but make sure you're wearing protective eye wear and gloves in case of sparks. Ensure you connect the right polarity to the starter terminal and the other to the chassis. The starter motor goes directly to the onboard battery so no problem provided you've hooked up polarity correctly. This will generally be sufficient power to activate the remote locking and superlock.

Ok il try the locking and unlocking, my voltage seems fine as when I can get into the car and turn Ignition On my volt gauge shows just under 12 which I thought would be ok. Where do I find the reciever

It's behind the headlining, in the middle of the roof at the point the roofline steps up. You have to drop the rear of the headlining down to access it.

Does it only happen in the one location?

Actually since posting this issue I havent had a problem but in saying that now I think about it every time the problem occurred has been in my drive way. It's at work for the rest of the week and I haunt ha d problem so will be interesting to see when it's back home

Mine Did the same thing after dropping the headlining and cleaning the contacts and earth I have had no problem since

So you think it might only be in your driveway?
Do you have a remote garage door opener? or something else generating RF
interference?
If it happens there again try sticking the key under the right mudguard and try operation.The guard act as a RF shield.
