Remote Key Programming

[Mike Scott]

I have a 1999 LS400 with 1 master key which starts the car & also has 3 button with all 3 buttons working. Needing a spare key I have had two keys cut by 2 separate Lexus dealers, both dealers have been able to programme the key to start the car, but have been unable to programme the remote locking. Any ideas what the problem may be & has any other member experienced this with a new key.

As I'm new to the club and posting topics, any help would be appreciated.

Many thanks

Mike

Go to Google and type programming remote locking for 1999 Lexus Ls 400 , several sites will come up check out the clublexus and the automotiveforum.com They are a good source.

Many thanks for your reply, but I have tried just about all the sequences posted on the Web, the door lock unlock dance, the brake & accelerator routine, that's why I then took it to a Lexus dealer or 2 Lexus dealers to be exact. Both dealers are able to get the new keys to start the engine but are unable to get the remote locking to work, which they can't understand as the original master key works fine.

My MK4 only came with one key, I bought a spare on eBay for £25, transferred the transponder to a cheap blank, which I had cut by a local locksmith. I then followed this procedure which worked OK.

Thanks, but that is one of the procedures I've already tried. I've just spoken to a car locksmith who thinks that the new keys may be transmitting on a different frequency to the original working key. I've made an appointment to have him check this out next week. Hopefully he'll be able to solve the problem, whatever it may be.

I've just spent 2 hours with the locksmith, who in turn had a long conversation with the last Lexus garage I went to. They came to the conclusion that the door control wireless receiver was faulty & needed replacing, as the keys were checked and are transmitting on the correct frequency, but they could not programme them. Lexus have discontinued this part (No.89741-50331/0) so I'm hoping to locate a second-hand one. Anyone know of one for sale, it's for a 1999 LS400 with a 3 button key ?

Problem No.2, Does anyone know where the door control wireless receiver is located in the car and how it can be removed?

Hi Mike,

It might be worth contacting Kyle McKee about the part you are looking for.

He breaks Mk4 LS400s and I have had a few parts off him for my Mk3.

His mobile number is 07769 355594.

I hope you manage to get the problem sorted.

Thanks Colin, I'll give him a call in the morning. Do you know in which area he is based?

Hi Mike

Sorry for delay in replying - he is based in Wybunbury in Cheshire.

Have you managed to get the part you need?

Regards

Colin

Hi Colin, I've tried the number you gave me several times without success, but I have located a part, it's in the post & on it's way to me. The car it's been in is being broken up, so the breaker has not been able to test it, however that's not the end of the saga. The car breaker also had a wooden steering wheel & wooden gear lever which I bought from him & as the original part I wanted was untested he threw it in free of charge. I expect to receive the parts on Wednesday if Parcelforce deliver on time. If all goes to plan I'm going to have a very happy bank holiday weekend.

Hi Mike

Sorry to hear you have had no success contacting Kyle - it has been about 18 months since I last had anything off him so maybe he has dropped off the radar.

Pleased to hear you have managed to locate a part and hope it works ok. Let us know whether it does.

Thanks.
