Key Fob (bought used one) program at home, can't turn on Ignition

[2002navyq45]

Hi,

I bought a used key fob on ebay, and program per program instruction.all function works good on the key fob, but it won't turn the ignition.

Why does it do that?or do I have to have the dealer hook up the computer to program it to use for that function?

Thank you all

The answer is: Yes

That key has a chip in it, that needs to be in sych with the ignition when you put it in or no start.

the only ones that can do that is the dealership..many charge for this but it will depend on the service writer and if you know one that is friendly. Usually if you buy it from them they will do it, you might have shot yourself i the foot buying it off e-bay as some dealerships charge $100 bucks to do this.

Take it to a writer who you might now, if not you might have to pay.
