Having spent a couple of hours looking for my keys this weekend (which i found) i have decided i ought to invest in a spare key. I've bought a key from ebay thats the same frequency as mine so i can reprogam the central locking part. But i've just spoken to my local Nissan dealer about getting a blade cut and having the chip reprogrammed so it will also start the car. After questioning me about which key it was (the squaree one with 2 buttons with white symbols on them-non NATS) he tells me that there isn't a chip that needs reprogramming. That i will be able to get a blade cut, fit it to the fob and the key will start the car. Surely this isn't right? I made sure that he didn't have the wrong end of the stick and he confirmed again that all i needed to do was have a blade cut, i could fit it to any fob of the same type and it would start the car. If someone could confirm that would be great. Cheers |

IIRC, al P12s have NATS (Nissan Anti Theft System),, which is basically an immobiliser system, and some have an optional Theft System, with alarm and such. Higher specced cars have the Theft system standard, I believe. Looking at the BL section of the electronic service manual, from page 151 onward, there is talk about registering the key ID. The square key has a small logic board inside, with a unique identifier, that has to be registered in the smart entrance unit. So no separate chip in the key that needs programming, the smart entrance unit just needs to be told that the new key is allowed to start the car. The procedure is on the forum somewhere. You need all keys for the procedure, as sometimes they loose the registration of the old keys. ------------- http://www.spritmonitor.de/de/detailansicht/635381.html" rel="nofollow">  Ex: Primera P12 1.9dCi Estate<b |

The key consists of two parts.One is the transponder, its the little black thing that sits at an angle in the casing close to the key.This is the NATS part which the immobilizer has to be programmed to recognize using Consult2. The other part is the remote controller, thats the circuit board you see when changing the battery,this part you can program yourself. Can only imagine he thought you were trying to build one good key out of two by swapping parts. Just finished reprogramming the remote on my key as it had died and lost the code but that only affected locking and unlocking the car not starting it. ------------- If in doubt give it a clout! |

Btw, i still think registering the key is enough. No proof tho, except BL-105 ------------- http://www.spritmonitor.de/de/detailansicht/635381.html" rel="nofollow"> Ex: Primera P12 1.9dCi Estate<b |

Have the same issue, in that the car came with only one key, bought two more off well known selling Site, and now need to get them paired to the car. There seems to be a number of different posts on how to pair the keys to the car, most seem to be for the older primera keys, are there any ones that are for these keys that work no problem at all, as being able to just get in the car would be a start if keys were lost.

So which guide did you use to program the keys please, my car has the same key as in the picture in this thread, so if yours is the same key type, I would appreciate the method of programming the keys, then I can go about getting the key to work with starting the car through the dealer. |

That is the transponder circled in the picture above.Every single one has a unique code built in.When you insert the key into the ign it is powered by induction from the coil at the ign barrel.The immobilizer and engine management units have to be programmed to identify these chips up to a max of 4.This has to be done by Dealer using Consult 2. Refer to pages BL-172-173 Any remote part of the key can be programmed to be able to lock/unlock any car but if the transponder isn't recognized it can't start the engine. Refer page BL-110 After recoding the first key which is in the ign barrel you can recode a second key leaving the first in the ign ( don't have to swap over keys) It's a bit awkward with the key in ign and you need to press the lock button fairly rapidly.Might have to do the sequence a few times to get it rite. ------------- If in doubt give it a clout! |

madaboutandroid just to be clear you'll have to start the sequence with your good key leaving it in the ign then program your other keys ,this should allow the other keys to open the car but not start it. ------------- If in doubt give it a clout! |

The P12 NATS system employs a rolling code for the immobiliser, and last time i checked, only Nissan could program it (Ford do the same thing aswell), the cost was about £200 per key, and they need the car for a few hours aswell. the good news though, is that if you have a missing key (or spares were not supplied with the vehicle) these can be deleted at the time. As for the edit button, non paying members don't have the option to edit posts. ------------- |

Thats why the remote can lose its code due to stupid things as in my case of lying on the keys and draining the batt when working on car , then having to re-sync to the car.Hopefully it won't happen too often as its a real pain in "A" having no flippin keyhole in drivers side and scrambling thru passenger side to open drivers door. ------------- If in doubt give it a clout! |

Uhm, maybe I'm not reading it right (could be, english is not my native tongue, so I might be missing some nuance), but the way I understand it, there is just one ID with each key, that needs to be registered. Normally by Consult, but the other way is used when consult is not available. In my copy of the esm, which ends at bl-170, by the way, no separate transponder registration procedure is mentioned. or is there an additional manual for consult where this is mentioned? Please correct me if I'm wrong, I 'm just trying to understand. ------------- http://www.spritmonitor.de/de/detailansicht/635381.html" rel="nofollow"> Ex: Primera P12 1.9dCi Estate<b |

Hi Wickydude English isnt mine iether ...... "Scots is."  I've got a 2001 and 2003 version ESM but use 2003 mostly as there is even more info in it eg autodimming rear view mirror not in 2001 version. Cant remember where I got 2001 version but 2003 is on this site. Page BL-173 also refers to "Consult II Operational Manual NATS" which I take it must show how to program for transponder. Hope this helps! ------------- If in doubt give it a clout! |

Als ik in het nederlands begin snap jij er ook niks van i know about the 2003 version, that came here thru me  just had another look. I use the bl version (lowercase) i get by clicking on the f9q/yd22 button. Downloaded that onto my ipad. That file is acutally different from the one you get by clicking on the p12 button (BL uppercase). Hence the differrence, the bl lowercase version is 10 pages shorter and does not have diagnostic 9. Probably some more differences... Do yoou have personal experience with that transponder needing separate registering? The reason i don't get it is that there is a section that says "remote controller id setup withou consult-ii". Ah well, anyone needing it can simply try it or first contact nissan. ------------- http://www.spritmonitor.de/de/detailansicht/635381.html" rel="nofollow"> Ex: Primera P12 1.9dCi Estate<b |

I understand --I use the P12 section. In the diesel section BL-163 refers to matching the Ign keys to the Smart entrance unit if the unit is replaced. The significant word here being keys. This is as it would be set at factory. BL-105 refers to matching the remote control to the system, this can be done without consult II. Service manuals can sometimes be difficult to understand as they are often translated from Japanese to English. I've become used to it after 44yrs as an electronic engineer but I get caught out at times. If you do a search with the word transponder you will find better detail on how it all works, they are similar to the security tags used in clothing shops (same principal) ------------- If in doubt give it a clout! |

Heres the easy way to think about it! If it was simply a case of putting a key in the ign and re-regestering it to work with NATS then what would stop someone smashing a window - regestering a key and away with your car? ------------- If in doubt give it a clout! |

That would be uncool but the procedure starts with the remark. " must be unlocked by either the multi remote or a transponder ok signal" Meaning that smahing the windows with a new unknown key will not work ------------- http://www.spritmonitor.de/de/detailansicht/635381.html" rel="nofollow"> Ex: Primera P12 1.9dCi Estate<b |

Yeah waaay over simplified, but I think I've found the page that hopefully will convince you. Deisel page BL-155 Consult-II Diagnostic Test Mode Function next to part that says C/U Initialization it says initialization and re-registering of all NATS ign keys will be necessary when replacing any of the following NATS ignition key / IMMU (smart entry) / ECM Also on Page BL-157 on the flow chart where it says KEY SERVICE REQUEST it routes you to consultII when asking for an additional key. Just the way its written in the manual and the old eyes arn't getting any better. Getting too old for this !!!!!! ------------- If in doubt give it a clout! |

So I can simply put the good key that came with the car in the ign and then code the other two keys to be able to lock / unlock the car, but will need to get these reprogrammed by the dealer to be able to start it? If so what is the correct possess for getting the two keys to unlock/lock the car please, I have just ordered two virgin chips to put in the keys ready to pay the dealer the £50 to code them, will get two blades cut this week then should be ready to go. Cheers Stephen

Page BL-110 in service manual is the flow chart for programming the remote control. It involves putting your good key in and reprogramming it first, leaving it in the ign and programming your other keys then switching ign on to finish. Just follow the chart. ------------- If in doubt give it a clout! |

| Hello, i have only 1 key and i want to buy one more. Can i buy a used key or i must buy a new one? And something else...the keys can be programmed by me (as described somewhere in thw forum-starting like this: turn key to on and off 6 times...etc) or must be done with the consult-II? |

reprogramming the fob to the central locking you can do yourself, pairing the immobiliser transponder needs to be done with Consult. two different things. Either with a new or a used key. ------------- http://www.spritmonitor.de/de/detailansicht/635381.html" rel="nofollow"> Ex: Primera P12 1.9dCi Estate<b |

Hi there, my key fob stopped working and i realised that the microswitches had fallen apart. So I ordered some from ebay to refurbish my old fob. Soldering was just easy as i have a little knowledge about this. My question is is there any way of testing the fobs are working before reprogamming procedure as my one now dosen't give me the single flash after perfoming the press hold the unlock button and then press the lock 3 times steps. Any ideas please as I miss locking and unlocking with the fobs

You may just be a tad slow with the 3 presses of the unlock button. ------------- If in doubt give it a clout! |
