    I'm pretty sure it has to be programmed by an authorised dealer, or at least with someone with a testbook computer.

    DO NOT buy your key fobs from anywhere else than an Independent LR garage or a main dealer.

    There are unscrupulous people on eBay at the moment that will use RF DATA recorders to obtain your key fobs signal, gain access to your registration document and then come and steal your Range Rover.

    Just a warning...just pay the £116 and buy it from LR and have piece of mind your beloved RR is secure.

    When my battery went dead for a few days I had to use the emergency access key code to get in, but the fob still wouldn't work until I turned the key in the door while holding one of the buttons.

    Wasn't this the process you go through to set the fob to the car? Wouldn't this have worked on a new fob that the car had never seen before?

    If the battery had gone flat for long enough for the car to forget my fob then wasn't my fob just the same as a new one?

    Why can't this same process be used to program the car to a new fob?

    to reset key you need access code which is made up of 4 numbers when you put key in the door you either turn clock or anti clockwise the number of turns of each digit of code

    Because of the alarm system used on the RR, the key fob can't be reprogrammed to the BECM. I looked into this when I bought mine as it only had 1 key.

    There are 2 stages to the alarm system, the first unlocks the door, which sometimes can be synched to another key as mentioned above by Mudflap, the second stage is when the key is inserted into the ignition barrel, the becm looks for a rolling code from the fob. This is unique and set to each BECM.

    The only place to get a key that will work is from LR. the blades are cut in the uk, the fobs are manufactured and programmed in Germany (apparantly) against the original build data (BECM Serial No.) for the car.

    I hope you didn't pay too much for the key, as I've seen them go for stupid money, and they aren't any use to anyone, unless you get the lockset, ignition barrel and BECM as a job lot.

    the range rover key fob uses a rolling code, the above procedure just re-syncs the code to the vehicle, it dont change the transmission frequency! The frequency it transmits on for your vehicle HAS TO and i think CAN ONLY be set by land rover using VIN and proof of ownership of course!!

    And of course the oher advice i would offer is NEVER buy a key fob from anyone else for your R/Rover, Landrover may charge but your assured it will work! i paid £103 last march, i dont know what LR charge for just the programing of the key but it may work out just the same or close!

    These keys will not work and cannot be reprogrammed despite what all these people say on Ebay.
    I have posted on this subject before, yet people will still part with their cash.
    Each key is programmed to a unique 14 digit lockset code which is programmed into the BECM and cross referenced to the VIN. This lockset code cannot and will not be doneby the dealer. I and others on this forum have gone through the process of buying new keys and they have to be programmed in Germany and take up to a week if you are lucky and are not "Knocked up" in the dealers stores or workshop. If you do buy a new key ALWAYS ask the dealer for the lockset code and make a record of it (Not in the handbook etc.!!!).

    so would it be right to assume that once a key is coded it cant be done again! hence second hand keys with the blade changed are no use what so ever? i would guess so! when i needed one i never concidered going anywhere else but LR but allas i didnt ask for the lockset number!

    Hi Redrange.
    Correct!!!- a fob with a different lockset code is as much use as a chocolate teapot other than as a means of holding the key. As you know, the keyfob is excited when it is put into the ignition switch to send it's "Code" to the alarm ECU via the BECM. If the code does not match that stored in the BECM then you cannot start the car.LR Engineers really went to Town on security on the P38. It is adviseable to have the lockset code as it would be required if ever the BECM had to be changed. The only safe way of buying replacement keys would be to buy all the locks from a vehicle, complete with the BECM and to be 100% safe, have the lockset code as well. Your LR dealer where you purchased your key from should have, or be able to get the 14 digit lockset code for you, proof of ownership may be requested. Alternatively, the lockset code may be retrieved from an UNLOCKED BECM by Test Book. If using Rovacom, as I do, the lockset code has to be converted by them to their own format. Unfortunately, gullible fools will still buy these fobs second hand and pay half price thinking they have a bargain, only to find it does not work, then put it back on the web for the next sucker that comes along.

    If people are so lazy as to not do basic research before buying then there will always be someone out there ready to exploit them.
    I had only 1 key with my car when I purchased it, and made enquiries at LR before getting a new key, to be told quite clearly that used keys can't be re-programmed.

    I made some enquiries at a local 4x4 breakers who offered me loads of P38 keys at £5.00 each, but couldn't guarantee the condition of them. With these fetching upto £60 - £70 on egay, its very tempting to make a few quid. by the way I have a length of previously owned rope if you know anyone who wants to part with some cash.

    Don't you just hate people that start threads without searching first, ask for information on a subject posted several times before, receive it in droves and yet don't reply with a simple thank you.........

    Perhaps it was not the answer they were hoping for Adam.
    I agree with you that all too often people come on the forum with a problem,get loads of response and sugestions for fixes then just disappear without advising the members who took the time & trouble to try and help out what the eventual outcome and fix was.This in itself is essential as other people with the same problem are left in mid air regarding the outcome. The forum is not just a helpline, it's a sharing of knowledge with the bit of light hearted banter thrown in for free.

    I know what you mean, I get the idea that when people go quiet after posting they have actually gone through with it already however stupid it maybe and were trying to drum up some moral support from forum members they'd done the best thing.....

    In this case buying keys off eBay and try and get them re-programmed.

    What's cheesing me off more though is I answered "gshacklady"'s question before here: key-fob

    Again got no thank you either......didn't listen obviously...still went ahead and bought keys on eBay.....

    Oh well......

    Sorry to say it, but they will just have to learn the hard & expensive way as we used to before the Web and these forums were around................

    For what is't worth, been down the same road. Bought second hand remote and from e-bay, phoned the dealer the remotes are supplied blank from the factory and are coded to the car, once done it cannot be changed (locked in), do not buy a second hand remote. Hope it saves you some money! Cheers, Ian.

    Just another word of warning, my dhse also only came with one key and after checking on this forum decided to go the right (and expensive) way and went to the local main dealer and ordered a new key off the vehicle chassis/identification numbers.Key only took 5 days to arrive, but then disaster struck !! The key didn't fit the door lock or the ignition lock and after having the code read by the dealer it was found that whoever had the car before for whatever reason had changed the locks and the Bcem brain !!!!!.I then had to order a new ignition/door lock to match the original chassis no.( door lock was us anyway) fit the new key blade into my old fob and kiss £115 goodbye. Should i sell my new fob on Egay ?:eek:
    ps. door/ignition lock quite cheap and easy to install.

    The keyfobs cannot be reprogrammed-full stop.
    If you know someone who does it then share it with us.
    The Main Dealers who are the link to Huf (The manufacturers) will not consider sending them off.
