Hi all,

Missus and I have recently moved house amd while sorting through loads of stuff she found a old Mk4 Golf key for a golf she no longer owns.

Among our family car fleet I have a Mk4 Golf Gti 180, which only had one key supplied with it when I bought,

The thinker in me says if i get a new blade and pay a key cutting place to re cut a new blade the same as my key I already have and then have a place reprogramme the key and delete all old keys off the car leaving my key I got with my car and this 'new' key.

It this all A load of effort for nothing? A chap locally in ringwood can supply a 'aftermarket' key cut and programmed for £96.

Thoughts please,
P.s reason for cheapness about the car is its a cheap shed, not pride and joy so not a lot of expense wants to be wasted on it but us :smile:

split the key so you can see the frequency range - if they're the same then you're halfway there. Only an auto locksmith will have the gear to recode a previously used key (in theory the factory gear only allows a key to be coded to one vehicle)

I had it done on our 2005 Leon Cupra R as Seat were too tight to supply 2 remote fobs on a new car!

2012 Seat Leon STILL has 1 remote and 1 solid key!

If the key has already been programmed to a car you cant re program it, get on ebay they have blanks for pennies as you dont need the blade bit

It's only the dealer's own kit that can't program a previously coded key - I think because it stores the immobiliser chip ID centrally to prevent cloning of keys in dealerships, but there's loads of car security specialist outfits that can do it. Starting with a 'virgin' immobiliser chip is potentially more straightforward, but since OP has a spare key and it doesn't owe him anything he might as well give it a try.

A specialist will be able to supply a key blank so might be best to leave it to them to swap, as they may be less inclined to be helpful if all the profit margin is being taken out of the job bar the coding itself

Resonable, I didnt think about it like that
Im not one to take money off a pro's bill that does a good job the key will be slung in the shed of doom and il just get a auto tech to code and cut me a new one!
Thanks all,
