Check this out, I know a guy who has identified the coding in the BECM that will allow him to take a set of P38 keys with the coding and program that set of keys to work on another Rangi!!! 8)
He is also working on a reset for the cluster. I can't give out any more info then that at this time..
but updates to follow..

Not sure where you are from, if you are in the States side, I did it last night on my 99 after replacing the Battery:

1. Insert the key with the Fob into the drivers side door lock.
2. Press the unlock button and turn the key Clockwise to unlock.
3. Press the lock button and turn the key anti-Clockwise to lock and the Fob should register (should see the side indicators flashing).

P.S. It may be that all you need to do is insert the key and press Lock/Unlock buttons. I always did it the way I described and it works for me.

Ha! Nice! Bet my local (sort of) dealer wished they could have done that for me....

I've been doing that for years. I have a selection of used key fobs ready to be programmed as & when needed.
So how can I get a second fob for mine noting the dealer who replaced the lockset some years ago didn't update the LR database with the new lockset code?

If I understand it correctly you need the matching BECM and key, so as to pull the key code from the BECM...and then address the key to your Rangi. The Key code currently used on your car will most definitely be in your BECM..

In that case can a key1 for example be reprogrammed to be a key 2.
Surprised Rick,you seem to have kept it quiet.There have often been questions about "Can a key reprogrammed to work on my RR".The answer always seems to have been no,or am I misunderstanding what you have posted :think:

I would think so but I'll check with the software engineer, and get back to you...

It is much safer to buy a Key programmed for your BECM. a key is what 175 and is super easy to synch so there is no reprogramming fees. What he is doing is changing the security code in your BECM to read the same code as the used key that you want to use. You can only use 1 security code, so you cannot use keys that don't "match" IE have the same security code. This might be fine and dandy until you are miles from home and your key craps out and you are forced to try and figure out how to get a key to match that code that you have reprogrammed into your BECM. Dealer orders by Vin and proof of ownership. I do not think that they can order buy security code. So someone might look into that to make sure.


If there was a way to reprogram the key fob itself to your existing BECM, then you are golden.

Simply order a new key with the VIN number you told the BECM guy to write down in the BECM.

So in order to get the new remotes you will physically need to reprogram the BeCM to accept the new codes from the remote?

You're somewhat right.

I get through a lot of becm's that come with keys. It's the matching key set's that come in two's & three's that are valuable.

There's two methods for programming them. Either extract the fob code directly from the becm of request the lock set bar code from any one of the main dealers that use me.

You cannot add an additional key to a set if it's not part of that set. This can only be supplied from the dealer.

For reference, we repair keyfobs for £50 a go.
