Infiniti 2008 EX35 - After Battery Change..BOTH Intel Key Warning Light & Security Ind. Light ON - Can't Start

Hi Everyone, I'm in dire straits...

Changed the battery in a 08 EX35 project car. Rode fine before having it sit
for a bit waiting for certain parts to come in. Had a mechanic come and
change the battery. All of a sudden now it doesnt recognize both original key
fobs. Guy went to replace the key fob batteries and still nothing. Went to the
manual key route, and it shows both steady the Intel Key Warning Light and
Security Key Warning Light being steady 24/7.

I tried it all... key fob against the start button, inserting it into the fob slot,
nothing. The battery got drained after three days because warning lights
were on all the time. I can't start the car and even had a locksmith with a
code machine for the keys come but he cant even get it to ACC - it's
constantly on "ON."

Is this a Electronic Steering Column Lock malfunction as the manual states?
Has anyone experienced also the loss from the key fobs connectivity after
changing the battery? Anyone have ideas?

I'm not sure what the cause of your issue is, but there was one guy here who had a problem with his electronic steering column lock.

See here:
escl-failed-t605982.html
He did mention that it was somewhat common with Altimas, 350Zs, and Cubes.

Not too long after, the same problem cropped up with my brother-in-law's Altima. For him, he just ended up removing the fuse for the ESCL once he was able to get it disengaged. I don't believe he's had any issues ever since.

If it's not the lock, I guess it might be the intelligent key system.

Good luck and let us know if you're able to get to the root of this.
