Thread: Cutting a new blade for Astra H key

Hi, Got a local auto locksmith to cut me a new blade and he also programmed the Astra imobiliser and got the central locking going too. Cost was £75 excl VAT. All from the back of his van, he came to my work to do the job. Great service, http://www.invictuslocks.co.uk/ if anyone looking for same service. Graeme

from my experience second hand remote fobs can be reprogrammed to another car ie the central locking plip the thing that cant be reprogrammed to a new car is the transponder which is in the key blade and disables the immobiliser, these are write once, there is a seller on ebay called keys2please I believe they can supply the needed key blades brand new and cheap

Yep, the Immob transponder is an RFID chip like those that set off the door alarm when you've nic - I mean forgotten to pay for something at Tesco's. Passive RFID's are write once & active ones are re-programmable. I have no idea if newer Vx immob RFID's are active, nor (other than Vx) where you'd get a correct blank passive one & have it programmed to your car.
