spare key
I didn't get a plastic key, but I did have a spare key (no chip) made, $1.98.
I hide it on the 4R, I Then hid one of the 'original' keys inside.
This way if is lock my regular keys inside, I can get in. Also, if I LOOSE my keys, I can get in AND get home.
If a thief finds the hide-a-key, he can get in, but can't steal it.
Note: You need one of the original black keys to program new keys (from the dealer) so that is why I hid a black key inside the rig.
