Yesterday I threw an old Murano key on top of a new one. (The new one
was reprogrammed when I lost a key last summer. I had just found the
"lost" key whose code was no longer valid.) The "new" key was working
all along...up to this AM. When I went to start the vehicle, it
wouldn't start as if it had picked up the code from the "lost" key! I
am down to one key now.
My question is this: Is it possible that one key's code could be
altered by being in proximity with another key?? If so, is there a
site I could go to to obtain further info?
Thanks!
Frank

My wife had the same problem after I inserted the wrong key into the
ignition of her 2007 Honda while moving cars around in my driveway to
clear the snow from the driveway. She had to re-enter the original key
code into the car. It was a matter of pressing some buttons on the radio
to insert the correct key code.
The original code came on a slip of paper with her keys. I don't know if
the Murano is similar, but you might check with the service department.
My only involvement in the whole scenario was screwing the code up to
begin with.

the found key cannot cause a working key to loose is programming.

The found key is still good, it just needs to be programmed.

Upon entering the programming function with the Nissan scan tool (consult)
all previously registered key are erased and the next step is to program all
the keys at the same time, if you had the other key at time of programming
it would have been registered.

It can still work, it just needs to be registered(programmed)

I can say that when I inserted my daughter's Honda key in my wife's
Honda, the key went in the slot and caused a 'beep', but would not turn
in the ignition. That's when I discovered the mistake. I then inserted
the right key and the car started. I then moved it back to its normal
parking position. The next morning, the correct key would not work,
requiring a reprogramming.

I'm not sure how Honda does things but Nissan will allow you 3-5 attempts
with an unprogrammed key , once the max number of attempts has been reached
the vehicle goes into "lock mode".

The vehicle can be removed from lock mode by using a specific set of steps,
it outlined in your owners manual, otherwise the vehicle will need to be
towed to the dealer will all remaining keys (if any) and have the
reprogrammed.
