You can get one at the dealership
They don’t need your key so you can keep driving your car. Required by dealer, VIN and proof of ownership
and A LOT OF MONEY
THIS IS THE MOST EXPENSIVE OPTION
WOULD MOST LIKELY BE $600+
and the wait time is months

I got one last year, I waited 16 months

the only upside is that you get to keep driving your car while you wait
(but don’t lose the key while you’re waiting).

Best option
in the event you decide to procure one from Needswings or another forum member consider getting two new fobs..

What’s the condition of the existing fob?
