there is no other way unfortunately other then trying to lubricated and loosen the lock , sometime we soak them overnight .

the only other way will be call a lock smith

or get another ordered from dealer but if battery dead in car that want work ?

do you have 2 keys for it or one , have you tried the other one ?

have you checked battery in key fob?
