There is not a "universal" glove box key.  The stock lock used code series SC, and there are several hundred possible keys.  There are no codes on the lock.  We generate keys for these locks on a frequent basis.  We can either make a key for yours or do a swap where we send a lock and key to you and you send us your lock for us to recycle in a like manner.
