Locking Problem

[breet]

basiclay the car wont lock with the key fob but the unlock button works and so does the boot,

Have you got more than one key for the car ? Is this a master key, do you know, or do you have a master ?

It sounds like the key has been forgotten by the car regarding the locking, and needs programming in again. The programming of the transponder (for the immobiliser) is separate, and I presume that's still working (i.e. it starts the car). My car did the same.

the car still starts just doesnt lock, how can i reprograme it or is that lexus that does it

The key reprogramming instructions are here. You should be able to do it yourself, provided you have a master key. You can tell a master key by the fact that the Security dash light immediately goes off when you insert the key, for a sub key the Security light stays on for a second before going off. Usually the master key is a three-button one, but this isn't an infallible guide.

So you just need to do the bit in the instructions about programming the key to the remote locking.
