Hi where I can read my key number? Thanks for answering

You can't. It's originally included in the block out plate which is knocked out of the key before delivery so that you can get the key on your key ring. You will need to go to a dealer to get this information.

even though its would be a pain in the but if your looking for the FREE answer you can take your passenger side door panel off an look at the lock cylinder for that door and the code for the key should be on there, i have do this one one of my cars when i lost the key, [thank god i had left the doors unlocked the night befor.]

Both my Pulsar NX and 300ZX had stickers in the glove box with the key number on it, but it's only there if someone added it at the dealer, or later. Otherwise, if you have an original key that is all metal, it should be on there.
