Question about 2007 Infiniti M35 Sport Sedan

1 Answer

Why won't my Infiniti M35 remotes work now that i put new batteries in them?

My battery on remote was showing low so I replaced the batteries in both of my remotes and now they don't work to unlock car doors or start the car. When try starting there's an error message on my dash that says, "Key ID: No". Car will start if I put the key in the slot in the dash so I know the car is in working order. Was I supposed to reprogram the key after changing battery? thanks!

If the remotes are anything like GM remotes - you will have to reprogram them both. Most Auto-Zone stores will do it for free - if you buy the batteries from them. Or google Infinity remotes and they will tell you how to do it yourself.

Hello! There is a Technical Service Bulletin (TSB) #12--8-2008 "Inoperative Key Fob"...It addresses a water intrusion issue...The Fob is more than likely damaged due to moisture...A TSB isn't a recall merely a notification of a problem...I would suggest opening the Fob and inspect for any green material in and around the battery contact area....Send a comment with results...Guru...saailer

This is most likely the battery getting low if the remote does work to unlock them then the remote itself will need to be replaced which you can get on ebay for reasonable which come with installation instructions.

Keyless remote will not unlock doors. Door was unlocked with key. Car will not start and the key will not release from ignition switch. Is this the anti-theft and haw do I reset it?

Check the car battery there is a battery in the remote as well but its to new to need to be replaced and so is the battery in the car It sounds most likely like there is a bad connection on one of the battery terminals on the cars battery if the bat is dead in the car the remote won;t work and if the bat is dead in the remote it won;t work but the car will hope this helps
