Last night I got home and my car would not lock on the fob(central locking remote). I changed the battery in it and it still wouldnt lock. I found the spare one and managed to lock it but I havent used it for years. I am concerned that if I unlock it again, I wont be able to lock it up again. Does this mean there is something wrong with the car or is it just the device and if so how can I sort it out? Any thoughts please?

if your spare one locked off the fob.
that leads me to think your 1st one has lost sync with the car when battery failed
you will need to resync the original fob with your car.

could you advise me on how to resync it please

unless its aftermarket like a clifford concept or toad then you will need to look up the manuals online

ok, thanks

mine is a sigma so its not a toyota one. im scared to go out and see if the 2nd one will work again in case it doesnt. i will have to see if i can get someone to come and take a look or wait till i drop it off at the garage for its MOT and hope everything is fine and i can start the car to get it there.
