Replace your Discovery door latch for less than £50 - the easy guide is here.
This job is way easier than you think. Especially with this video to look at!
After 150,000 miles and changing all the other door locks, it's time to swap out the rear door latches on the Land Rover Discovery 3. I currently have to manually lock all the doors and if I use dthe fob to remote lock it, the alarm goes off and they don't lock.
For around £50 each it's made my life so much simplier and I can remote lock the car without the alarm going off continually!
