Well done Renton, I also baught a keyfob with blank keyblade from fleabay and learned the hard way if you need a second key for your car buy it from LR, so thanks to you experince I will keep the fob for when one of the other two keys fail. Why have your keyfobs failed, did you never use the failed one? Seeing they need charging while in the ignition?


I use them both (SWMBO and me). They both gave up in a 12 month period. Actually, the battery gave up I guess. Tried to replace the batteries but that didn't work.
So it's fair to say that Keyfob's have a approx. 5 year life span.

I'd better start using the other fob for a while then - don't want it dying on me ... Whistle

At the expence of menber Rasu52 it is also confirmed (which BBS Spy already claimed) that a secondhand/learned keyfob will never work on another vehicle.

Hello, so finally where can I get the best price so I can buy three unprogrammed remotes since my two original ones have holes due to my wife's nails!!!
All I need is the remotes, even uncut since my blades are perfect yet.
Thanks everyone.

You can have a look at your favourite auctionsite but if you are looking for 3 I suggest you give TheLargeOne a call at Yeovil. He will surely make you a great offer.

I've just stumbled across this thread trying to find out how to fix my key.

I've opened up my key (with not that much violence) and found the fault to be a snapped terminal on the battery. When you have them apart you can see that the battery in welded into a plastic housing. The housing clips to the PCB and there are two solder lugs through the PCB to supply power. Except in my case only one lug is attached to the battery. The other is snapped off underneath the battery. The soldered joint to the circuit board is fine and in certain conditions the battery touches the lug and it works, other times it does not.

I suspect this is a common problem as other seaches have shown key fobs which fail but start to work again when bashed against a hard surface, etc.

The solution is to remove the battery and replace. However, they are not available over the counter at the places I've tried locally. So my bodge is to increase the size of the snapped lug by building up solder. Now contact is made even if the battery shifts position slightly. This is a short term bodge only until I can get a new battery.

Cheers, Steve

Is there a knack to opening them up? Did it go back together ok or does it look like it's been run over?

They aren't too hard top open - or at least mine wasn't.

Flip the key out and hold it so the writing is facing you. You will see a gap between the key and the writing. I inserted a broad flat tipped screwdriver in there and pried up & down. I tried to keep the screw driver deep in the slot so any damage would be hidden. As the gap grew I used my fingers around the edge to pull slowly.

I went back together fine - it did take two goes to get the key to flip out but that was not a problem. My advise is not to glue it shut until you know it is working well. It will hold together for a test without any glue, but I used mine for a day with an elastic band holding it shut. Once I was happy I opened it again (almost no force this time) and applied a couple of drops of superglue to the previously glued surface.

It looks almost as if it didn't happen. If you look closely and know what happened to it you can see the slightest tool mark where the screwdriver levered against the edge, but this is not significant.

I wouldn't like to swear to the waterproofing now...

Cheers, Steve

I'd wary of buying the second-hand/used fobs from eBay; re-coding them is by no means a given.
Unless the seller is offering a guarantee, stick to ones described as "new" or purchase from the site sponsor, TheLargeOne (Yeovil Land Rover Parts Manager).

Wife has just lost her key and the car is stranded as I've got the other one with me (in Canada, just for good measure). Any ideas how to source a new key at a reasonable price? Looked on fleabay, but they are all used so presumably useless. Big Cry

Would think your supplying or servicing dealer would be able to arrange such as a rush job on the basis that you are known to them, but Friday afternoon doesn't make it easy.
Couriering yours back is probably faster!

Just found a new key for £75, about £40 to get it paired to the car. Home in the morning, so will get it fixed early next week. Thumbs Up
