If you want your door and bootlid to have new or matching keys this is the easy way. The standard set includes two barrels with matching keys. This is only suitable when you require a drivers door and boot handle to match on MK1/2 cars only. This fits Vans/Estates also.
If you have had to fit a locking handle on the passengers side there is not a kit available for all 3 barrels-The Mk3 kit for wind up windows is different.
