Description

I've installed a "Start/Stop engine button" kit over the place of key cylinder. To retain immobilizer capability I've designed this "extender". The hole in the coil fits my Mitsubishi transponder key. The frame over the coil fits my car's panel dummy cap dimensions. The coil is electrically connected to a wire been wrapped around genuine Mitsubishi immo coil located on top of the key cylinder. I've tested this extender and it works great!
