Hello, my name is XXXXX XXXXX I will try help you with this.
Do you have the five digit security code from the vehicle's security card.
You were wrongly informed.
All you can do now is either get a locksmith with suitable coding equipment or use a main dealer.
If you had the code you could have bypassed it.
In that case you have to contact a locksmith or main dealer.
It probably wont work but what have you got to lose.
It doesn't usually work.
Do you have a spare key you could try?
Try disconnecting the battery, you might get lucky. If not then it has to be locksmith or dealer with coding equipment.
Hope it goes well for you.
please remember to rate my assistance.
