If you have a search on here there is a re-training guide to recode the keys.  It may be the key receiver unit has failed?

Another thing to try is to drive the car away a few miles and try again.  It shouldn't happen these days but there was a serious issue with keys working in the old 418MHz channel, hence cars moving to 433MHz.

There were press reports last week about key jammers being used to prevent cars being locked (or unlocked if already locked) to allow for thefts of the contents etc. >:(

Excellent news.  Keep an eye on it in case it's the inductive charging ring around the ignition switch that has packed in.  I don't know a simple way of testing it.
