the red key can't be cut easily, if he knows a way then he needs to tell us all!
The red key is important if something goes wrong with the ecu, immoboliser etc... and if it does ur looking at a small fortune to put it right without the redkey, even at breakers prices. (new locks, ignition barrel, ecu etc...)
The red key doesn't just start the engine, it can reset the immoboliser and i think it does some tuning stuff (not sure tho) so don't just accept it cus it starts the car, as keys to do this can be made cheaply at timpsons etc...
If he definately hasn't got the red key, then u need to haggle the price down a bit more.
Keys:
REQUIRES RED KEY: if blue key has a triangle with two circles around it.
DOESN'T REQUIRE RED KEY: if blue key has a 2 with two rings around it.
If anyone thinks this is wrong let me know, cheers all.
