Yeah.
Go in the boot. Pull back the carpet and you'll see the pull cord behind the bodywork which will release it by hand.
You'll see the 2 screws holding it to the bodywork with the pin that sticks out and holds the cap.
They get shitted up for some reason, take it off and tap it a few times and try it in your hand by locking/unlocking the car with the keys. If it doesnt work at all you'll have to get a new one, which is what i had to do.
