Spare key

[messi]

Hi guys

I hope someone can help. 

I want to get a spare key made for my 1999 ls400. The dealer has quoted me over £200, that includes programming it. 

There must be a cheaper way to get the key made and programmed. Can anyone help me please? 

Thanks in advance

Hi

Yes it can be done - you will need one working remote key.

Buy a second key and follow the instructions in the link below by Haylands - i done many years ago: the central locking part was easy -- but the immobiliser part took about 20 attempts and it finally worked - good luck

It needs to be the 3 button master key to clone from it.

And I also remember reading make sure the key you buy has a triangle on the unlock button

Messi, I was quoted over £200 from 2 different cutters one them was refered by Lexus Edgware Rd

Abit expensive isn't it just to cut a key and program it. I'm just going on eBay to find a key

They way I done it for my R reg LS400 was

Buy a used remote key

Buy a new uncut key

Transfer the transponder over

get the blade cut locally

program the key

I can't remember how much it cost because it was over 9 years ago

That's what I did with my MK4, a key from eBay which cost me £25 and a key blank for about £4 and cut by a local key cutter for £8.  The reprogramming took a few attempts but did work.  The vital component is the correct key which isn't always easy to get, and a US one won't work.

Very interesting, >but< if the transmitter has been used to lock it that key will not work in the main drivers door. As it happens I also have a spare key but it will only open the passenger door.

The process of programming a key is a strange system involving split second timing and a confusing set of steps.  The vital component is the right key, regardless of the car it came from.  The other essential component is a working master key, without that it simply won't work.

Ok I've just recently had a key done for my ls450 and it cost me 150.00

He supplied everything inc programming and complete key and 12months warranty

Got him from eBay and all I had to do was take car to him swathe working key fob took him 20 mins.
