I have a nissan murano 2005 and the remote control does not work though the battery is new

You can try to disconnect the Battery for several minutes and then reconnect to reset the BCM. If this doesn't work, you'll need to have the BCM tested or replaced that controls those functions. The Murano has an especially sensitive electronic system and many parts operate through Body Control Modules. (BCM)s

Using the proper equipment, these items can be re-set, if the BCM is not bad and everything else is working properly.

If you've done other repairs recently, double check all of the ground wire connections as this can also lead to things operating when they shouldn't.

Mine did the same thing. I had the battery replaced on the controller.and it still beeped. Then I took my key and put it in the ignition, without turning the key and took it out. Did this like 6 times and the long beep finally stopped.

They say to use a dime to open it and then just take the batterys with you there is two of them and put the new ones in it will cost about 10 bucks for the batterys but they last 7 or 8 years

(Assuming the lights/battery are good), First, try a different remote/key. Your remote may be bad.
If the problem is your remote, get a new one ASAP, since you have to have a working one that the computer recognizes in order to train it to recognize a new one. Otherwise you have to replace the entire computer module ($$$).

If the other remote does not help, try disconnecting the ground cable on the battery for a minute or two, then reconnect it. If that fixes it, talk to your dealer. My 2005 Chrysler T&C had a similar problem, the door locks are always powered, but the computer monitors how much current they draw. If it is too high, the computer disables them to save the battery. In my case, the current limit was too low, the computer had to be reprogrammed by the dealer.

Liftgate is connected to front RH's door actuator thru back door's "opener switch". Replacing the passenger's door lock actuator will solve the problem.

are the batteries in correctly and is the button in good working order

Replace the remote battery first, then the remote.

the new seat probaly has diffarent features mabe one has heated the other doesnt i would get a taredown manual and check the wiring diaogram and see what is shown from one seat to the other

have you tryed and reprogram it? if you have the fault lies in the the system and you need to replace it because it is a factory error.
