Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hey there, thanks for the question.
You need dealer level equipment to program a key. You need to get decode the 5 digit BCM code and use the Pin read to register the new key. Anytime you register a new key it DISABLES all the old key registrations.
Some locksmiths also have the ability to convert pin reads and register keys. Their price is about the same as the dealer to register a key, but at least you wouldn't have a tow bill that way.
