#1 of 13 Key to be reprogrammed by kmk Aug 22, 2006 (3:51 pm)
My 2005 pathfinder would not start, it took several times for it to finally turn over. Same thing the next day, Brought it to the dealer, they said it was some sort of safety thing???? They had to reprogram the key??? My husband thinks they are full of it! Any responses????

Replying to: kmk (Aug 22, 2006 3:51 pm) The vehicle imobilizer system uses a chip in the key (no battery). There is a sensor unit in the steering column that looks for the "correct" key. If it doesn't find it, the vehicle will not inject fuel into the engine, and so, will not start or run.   I have not heard of this being intermittant (you said it did start eventually), and if it was I don't understand why reprogramming the key into the system would fix it. There can be as many as four keys programmed into the system. If you have trouble again, try the other key your vehicle came with - not the valet key (all metal), the one with the plastic "handle". You'll notice a blue (or perhaps another colour) plastic plug on the handle, covering the chip.   I would suspect flooding as the probable culpret to a vehicle being hard to start.

Replying to: kmk (Aug 22, 2006 3:51 pm) Same thing happened to my '06. Some days it would start, some days it took me taking the key out of the ignition and putting back in to start. I tracked it everytime and logged any similarities...(ie low fuel, cold, etc) but there were none. Finally, I took to one of those car washes that the car goes through on it's own. When the dude couldn't start it, I got nervous the next car was going to hit mine so I had had enough. Took it in, they thought it might be the key needing to be reprogrammed so they did that. Sure enough, have not had any problems since. So I guess they are telling the truth!   PS. They service department guy that took our vehicle was adamant that it couldn't be the key. But when they called me back, a different guy said that it can be the key. So even they don't really know....but it works now so I'm happy!

#4 of 13 Re: Replacement Key Question by jnilsestuen Dec 26, 2006 (7:08 pm)
Replying to: kmk (Aug 22, 2006 3:51 pm) I have an '01 Pathfinder SE. I just lost one of my two keys and want to purchase another spare. Is there any way to do this other than paying the dealer? I see key blanks for sale at several online locations but am not clear what is then required to get the key cut and programmed. Do I have to head to a dealer for programming no matter where I buy the key? Any advice would be appreciated.   Thanks, Replies to this message: maximalou (Jan 17, 2007 6:56 am)

Replying to: chris67 (Nov 17, 2006 4:14 pm) I bought a new '06 a month ago. Two days into owning it, and it won't start. I took it back to the dealer, and had the keys reprogrammed, and haven't had any trouble...until now, a month later. I was told previously that if reprogramming the keys didn't work, then the computer was going to be replaced. I guess I'll find out what's going to happen tomorrow, when I take it back to the dealer.
#8 of 13 1995 Pathfinder Keyless Entry reprogram by jkow3 May 01, 2007 (8:33 am)
I have been to dozens of online forums that talk about how to reprogram your keyfobs and I believe I am attempting it correctly. Steps: Turn key to ON position, then back OFF. Locate box under drivers seat, push and hold down button until you get the 5 bursts. You hear a series of beeps. Press your LOCK/UNLOCK button on keyfob. This associates the 2 devices. Turn key ON then OFF again. I actually get a response from the BOX when I hit the button on my keyfob, but it still will not work. It leads me to believe I am doing it right, but there is some kind of problem with the remote BOX.

Replying to: chris67 (Nov 17, 2006 4:14 pm) I was having the same problem with my 2005 350z. I took it to the dealer where I bought the car and they said they have to reprogram the keys and will take an hour and half. Still under warranty but they said that is not covered under the warranty. I have to pay $50. Not a lot of $ but I bought the car in 06 and the sales peolple probably lost the keys.
#10 of 13 leaving a key in the ignition off and then remote start by 99accent Sep 02, 2009 (11:36 am)
I have a remote start after market on my 2003 pathfinder if a transponder key was left in the ignition by mistake in the OFF POSTION, will my remote star still start the car or will it somehow confuse the system seeing 2 keys one in the remote start under the dash in the little box where they use an extra key for the remote start?
