Hello chaps

My sister has gone and got herself a first car, Corsa C 1.0 12v. Seems a decent one, very low mileage, few niggles, but good for a 15 year old car.

Key started to get a little troublesome, the spare works perfectly. So... whats involved in getting a new key coded? I'd assume it's the same basic setup as a MFL/FL Omega. The physical key works fine, buttons etc, it's just the chip which clearly isn't talking to the immobiliser 100% reliably all the time.

So whats her options of getting a new key coded, anyone fancy the job / recommend anyone?

Try the key the other way up if it does not read the chip ,if that works mark the key for future reference 
some key fobs block the ID40 chip signal in one way .
as you have 2 ID40 chips ,one in each key ,just a new case may tidy things up 
if the spare key is not a door remote and the main key is ,you could swap ID40 chips .
a completely new key wold need cutting and programming to the ecu if you don't/can't transfer the guts (car pass required i'd have thought)

First step is to remove any other car keys from the keyring

This info has been passed on, ta chaps.  I'm try and get some feedback if these tips work...

Tech 2 can do the work and basic diag via the live data, needs the car pass for security code

Who's furthest north on here with Tech 2 services? as the car's in Cleethorpes, North East Lincolnshire.

Suppose taking a day trip to travel to someone would be an option (would be her first long-distance drive) too.

Well, technically, Highlander is further North.  But too far North for Lincolnshire

[Diamond Black Geezer]

Grand!

I'll pass the message on. By the way, depending what's actually required (I'm still presuming a new chip only, paired to the car) what prices are we talking - happy if you'd rather send info via pm.

Thanks, Mr DTM

Check simple stuff first, such as the connections from the battery to the circuit board. I have an Omega key which is currently giving problems due to the connection between the two.
Hopefully a dab of solder will fix it.

[Diamond Black Geezer]

More good points! I'll pass that on too. Her feller is well into his computatering, so fairly handy/familiar with squinting at PCBs and the like.

[Marks DTM Calib]

Corsa C has a different battery setup which is not soldered to the PCB so should be ok
