Thread: Flip key conversion for pre 2005

I'd have thought anywhere that can do the double sided keys Holden have been using for years would be able to do them, just the blade is a bit wider than the Holden style and they might need to pop out the retaining pin to remove the blade from the flip to get it to clamp into the machine.

The design isn't anything overly complex, but one of those where I'm betting saying it's for a Range Rover probably ups the quoted price considerably...

As in the title this is to convert a key from the old style BMW key to a new flip key, its NOT for a replacement.. got all the info on a UK forum so praise should go to them..

So I ordered this key from Range Rover Flip style Remote (Replace the Remote head Key) 433mhz **auto keys,transponder keys, remotes control,locksmith tool,chrysler fobik supplier, making sure its the 433Mhz... Asked for the FAT style blade (wide type B format) as the UK forum received the slim stlye blade and for the key to Not be glued..

I order two ($88 for keys and postage) and they arrived in about 5 days to Tassie, which it very quick..

I had to try several Locksmiths until I got someone to cut the new blades. lucky there was just such a place here and he only charged me $10 to do them both.. Pull apart your old key to get the transponder, it's under the circuit board.
Put transponder from old key into new key, it goes up the front under the circuit board, the thin end (near the flip key spring) with the black looking chip on it, this it the battery charging coil, the transponder chip must go here or your battery wont charge! (one of my new keys had a new transponder chip already there so I put mine there in its place, the other didn't ??). Put new cut blade in. Put cable tie back on, don't glue anything till ur sure it all works. The flip key is fiddly cause u have to put it on the spring and wind it (you'll know what I mean)
Follow the reprogramming sequence:
Programming a new Key

1) Get in and close all doors. Turn ignition on and off quickly and remove the key (all within about 5 seconds). (Don't start the car, just turn until dash lights are on)

2) Within 30 seconds of turning the ignition off, while holding down the "unlock" button, press the "lock" button three times. Release the "unlock" button. (You may or may not get the confirmation from the door locks they should lock and then unlock.) Holding the key at your head level provides best results as the key sensor is in the side window pillar.

3) Repeat for each key you want to initialize within 30 seconds after the last one you initialized (if you have more).

4) Right after doing the last key, quickly put the key back in the ignition and turn it on/off again .

Some work first time and some take several attempts but listen for the door locks to cycle then do the same on the original key.
Mine all worked first time

Put in ignition,

Go for drive to charge it.

Now under take this at your own risk!! I was successful and have had no problems.. others on the other forums in the UK have had some issues though..
If all is going smoothly and you are ready to glue the case shut , sand around the lip on each side of the case so the glue has a nice rough surface to bond to..
Thats It!!! hope it helps someone..

Cheers

Just an update for other's information.

Got my blank keys/remotes from Beijing today.
When I put the Chinese keys side by side with no 2007 L322 key I cannot tell the difference in any way. I've been to China a few times and seen these things made on the footpath. They are an amazing people!

Even though I specifically ordered the 433 mHz model they sent me (according to the invoice) 315 mHz remotes.

Luckily I paid with PayPal so probably covered by their policies.

It'll be interesting to see the Chinese handle this stuff up of theirs?

And, has anyone communicated with them about programming the chip to make it work without using the chip out of the old key?
I've read on the RangeRovers.net site where they are doing the chip programming themselves.
