4 button key programming

[Syed]

Hi guys,

I have a 2008 Alphard 2.4 and it only came with 1 key and I’d rather have a 2nd than have to fork out a lot of money if the only key goes missing.

bought a replacement key off eBay and have had it cut. It goes in the barrel and works fine but engine won’t start. I’m guessing this is the transponder issue?

 

anyone know how I can program the transponder in the new key?

 

I’ve found a few different versions of this but can’t seem to find the correct one and I’m not doing the sequence correctly.

 

any help would be much appreciated.

Hello Syed,

 

Welcome to the Forum

 

Yours is a common problem among new owners.

 

Assuming you have the correct 4D67 chip in your key; you need an Auto Electrician and 80 to 120 pounds !

 

You could try Halfords or Timpsons, but they won't do it; neither will an official Toyota dealer.

 

I cannot remember whether TechStream (Toyota software) allows you to do this or not.

 

As I said, this is a common issue; try searching this Forum to improve your awareness.

Hey mate you need a locksmith who has a correct tool and knows how to programm the immibilizer or a willing dealer. Essentially you'd need to add the new transponder to immobilizer memory in order for it to work.

 

If you are tech savvy you can buy a cable from Aliexpress and do it through techstream as well

I did read something about this…

thanks

Hi,

do you have a step by step guide by any chance?

I’ve ordered the cable and once it arrives will have a go. I have a couple of friends who are very tech savvy IT pros so if all fails I’ll be calling on them to come over 😁

thanks for your input. Will be back with updates.

Type 'techstream key programming' in to YouTube. 

Plenty of videos to suit all toyota key types. 

The procedure is pretty much the same for all, it's such a quick process writing it out would take longer.

I’ve had a go couple of times now but for some reason not quite there yet.

the program is having trouble connecting to the ECU… there are so many tips (almost too many) online about what it could be but I will keep trying.

eBay seller is very helpful and given me a new set of license keys so I can install Techstream on a better laptop.

inside does it have a transponder chip?? some are replacement keys where you swap your old transponder in to the new shell. Some people break their key shell so you can buy replacement shells  with blank blades with no chips in them. So best check first

 

some key companies can clone the transponder without the car present as well

Hi guys,

I’ve managed to successfully program my key to start my car ☺️

was a bit rocky but got there in the end.

the most challenging part was the driver.

Techstream does not recognize the driver and you have to install in manually.

 

maybe someone can help me to program my buttons on the key? Key starts the car but wont lock or unlock the doors 😂

 

thanks.

Hi,

just wanted to give a breakdown of the costs involved in getting/programming a extra key. All costs are rounded up/down.

key/shell/chip £20

key cutting £10

MVCI cable £40

remote central locking programming £free

took about 2-3hours because of driver issues otherwise can be done in 10mins.

 

all in all I think I’ve done well. Costs of replacing a lost key would have been extortionate because I didn’t have a spare.

I hope this helps anyone looking for something similar.

hi guys,

 

I’ve now completed my programming of my key fully.

I found a post on here which said to try this:

I’m Not sure how to credit the person who’s thread it was.
