my brother had an extra key fob for his 2k2 max at my house. i think he ran it over because the keyring loop was broken on both the remote and the key.

after reading a how to on programming the remote and doing it (had to clean the inside as well) i cut a loop off an old blank key and used piece of a sharpie to fill in the rest. and it's all held together with super glue.

not the prettiest thing in the world but better than paying for a new one..
