it's the one which is used to pair other keys transponder codes to the immobiliser.. so you put in the purple key, touch your left elbow then your right knee, then put in a key you just bought from hyundai and touch your right toe and your immobiliser then know's that this key is ok to turn off the imobiliser
(instructions may have been made up to explain the process without knowing the true sequence)
Yeah but its not cheap to get another Transponder Key cut and Programmed Every Locksmith I visited Wanted £60. God knows what Hyundai Charge. I got a Spare non Transponder Key Done for £5 just in Case I ever Locked the main Key in the Car as I have a After Market Alarm That relocks the Doors after 30 seconds and Arm the Alarm. Which Could be a pain As I only have one Master Key but it never Leaves the House unless I am In the Car
It can be turned off so it does not lock and rearm I turned it on To see what is was like be I don't like it but it saves me leaving the car unlocked because I have pressed the unlock button as I have put the Keys and Fob down in the house and not know the Car was left unlocked over night in the street. This way atleast I know it will be always locked and I keep the Non transponder key in my Wallet just incase it locks with my keys in the Car.
PM me your Alarm it may be the same as mine and I have all the install instructions as I email the Alarm maker and asked for the install instruction, I also have the operation Instruction if you dont have those
My Toad has the auto-lock feature, but it only locks either after you turn the ignition on (anti-hijack) or if you unlock the car but don't open the door, it thinks your silly and unlocked it by mistake and locks again.
