Lupo 1.0 lock issue

[mcflycossie]

My son has a 1999 Lupo which has 3xkeys which all seem to unlock different doors etc. 

The driver's door lock no longer opens by the key so I am assuming the key barrel is knackered and needs repair. 

My son however is sick of having multiple keys so I started to search the internet and noticed a full set of locks with keys available. Is it as simple as buying the new lock set and switching it all over ?

Yes and no. The physical lock is the easy bit (apart from the steering lock barrel is tricky). The fun starts when you want to match up the ID chip in the key to the security system. You'll find that the key that works now (starts the car) is probably the one to keep, then simply recode all the other barrels.

You can take the barrels out and move the tumblers around to match the code on the steering lock key. Start on the driver's side lock and work your way round the car. It doesn't take too long to do. Just a bit fiddly.

Ok thanks. How do you match the code to the steering lock key ? I don't think the car has a alarm as such.

I've never ever cracked how to do it, and have really worked hard at doing it. You need to recode the car's computer to recognise the chip built into the key. Google ID44 and ID48.

In a nutshell, the easiest route is to get the key copied that works in the steering lock. Find a specialist key copy place that will do it WITHOUT dismantling the instruments. Best price I've seen is about £60 a key, including computer pairing up. Let us know how you get on. First step is to rebuild the lock barrels which is a DIY job.
