Originally, the key and the plastic are moulded together, so you cannot just change the plastic without cutting a new key.

The keyblade needs to be cut at your local dealer or qualified locksmith. Most locksmiths now provide such services, and charge much less than the dealer.

The key shell does not included the internal module and chips, ONLY shell case.

It only take 2 Minute to do yourself. No Programming Require.
