I am moving into a second hand home which has a UPVC front and rear door.

Is it possible to buy new locks and fit them to the existing doors?

I will feel happier once I have done this as over the years family/people may have kept hold of a key or 2.

you just need to change the euro cylinder measure the size of the existing one first, to change it is easy, insert the key in the lock locate the one screw holding the lock in position, Its usually a long cross head machine screw, remove the screw, and turn the lock with the key until it comes out its usually the 2 o clock position, to fit the new one just reverse the process

Thanks a lot for the reply.

After your post I went out and found some Euro Cylinders at B&Q, they varied in price depending on size between £10 and £20.

Well worth spending on for peace of mind.
