If your Discovery 2 key is getting stuck in the key barrel intermittently, you often times just need a new barrel tumbler assembly.Fairly simple install and is a fraction of the cost of the genuine part (if you can find one).Requires no key programming and comes with a replacement barrel as well as two new spare keys.Designed specifically for Land Rover Discovery 2 (1999 - 2004)Note: During installation, you will find that this retrofit kit looks different than the OEM tumbler, but it works just the same. All of your systems will stay enabled, but you will have two connectors left over after installation that will not be connected to anything.
