TD5 door lock replacement

The driver's door lock on my 1999 TD5 is broken. The key just turns in the barrel. It still locks on the remote but this sets the intruder movement alarm which means I cannot leave my dog in the car and lock the car.
Can anyone let me know if it is an easy repalcement and how do I go about matching it to my key. I don't fancy having to change the igntion lock as well if the key needs to be renewed.

Hi if you speak to your L/R dealer with your key No they should be able to supply you with at replcement lock for you door.

hope this helps

Many thanks Dave, I hope it is that easy and not too expensive.
