New 2020+ Start-Button Conversion

ahmed24 · March 22, 2022

Ever since I saw the concave design of the newest style start buttons, i've been on a mission looking for it secondhand. I prefer the hybrid blue version as the colour on that is really nice and goes with my blue theme. I really like the amount of depth the new design button has. It's really hard to find these buttons second hand as they are very new. The non-hybrid version is silver in colour and also looks really nice. I was lucky enough to be able to source 2 second hand hybrid ones from Lithuania for just under £50 GBP and with a very light polish made them look brand new.

Unfortunately the buttons are not direct plug and play. The new design button has completely different connector and number of pins. The PCB design is also different. So, since I really wanted this, I set out to convert my 2is button and below are some pics of my end product that I wanted to share. There is also a video demo which shows the backlight and colour sequence. Really pleased with how it turned out. Button looks, feels and works exactly like OEM

Looks impeccable Ahmed, all your tasteful mods have probably given you the best 2IS in the country!

Woooaa this looks so premium @Ahmed well done!

I am looking to do the same thing but with the grey colour button, part number 89611-11010

How complicated is the re-wiring job? Did you have to modify the old PCB to fit the new button enclosure?

The grey one below is when this design was introduced for the LC and with the LC hybrid they made the blue one. Which then started to be introduced in other models like the 2020+ UX and RX. A friend of mine wants to get the grey one for his ISF. Unfortunately in the UK almost all the newer models of the lexuses are all hybrid so finding a second hand non-hybrid version button from a 2020+ car is going to be practically impossible. The only option for second-hand would be to import from America as they have plenty of non-hybrid variants still going.

There are two ways to approach it, one is to build a harness to convert the existing wiring connector to work with this. But instead what I did is dismantled a spare 2IS button completely and used the entire core of that button and just transferred over the button and outer bezel from the new button. Unfortunately it's not a straight fit and requires a lot of hacking and modifying of the white plastic frame that holds the button. But once complete you are left with a new style button on a OEM switch making the entire thing plug and play and OEM looking.
