The newly aquired 98 Accent Coupe came with a blue-handled key and two black ones; both black ones would unlock the doors but not lock them, ( they can, of course, be locked on the button ) the blue key would lock & unlock doors; all keys work in the ignition.
Mindful that the blue key might be precious as it came with a metal tag embossed with a code, I called round to the local locksmiths today to get the blue key copied so that I might leave the original at home. ( After several embarrassing incidents in the past I *always* make a point of locking the door by means of the ignition key ) The locksmith X-rayed the key, or something, and confirmed that it had a transponder, but she could copy and chip the new key at some cost.
'Never mind, just copy the key so it will work the doors & I'll pair it up with a black key for the ignition' said I and so paid £5.70 for a basic non-transponder key.
Naturally I tried it in the carpark before I left, the new key would lock & unlock doors but while the engine turned over it wouldn't fire, just what I expected really except that when I got home and tried it again it started the engine perfectly!
So I don't really have any problems, just puzzled about the whole set-up...
Are all modern cars suppllied with immobilisers as standard or are they still optional i.e. is it likely the Hyundai has one? ( incidentally it is the very basic model without alarm or central locking ) If it is working does it inhibit the starter motor or the ignition coil or both? If immobilisers fail do they fail safe, i.e. car will start?
