Great quality product !

Worked great even helped me trouble shoot my other issues ! Great quality and very helpful responded very fast for all my questions

Plug and play no issues good quality work.

I can’t even describe how it feels like driving with my driver side window down again. Making drive thru’s available again for me 😭 5/5 rating

Upgraded my s13 front end to a kouki setup and needed a new wiring harness for the new lights and this worked exactly as described! Super happy with the quality. Shipping was fast! Would recommend.

High quality, plugged right in, no bullshit! Also very responsive during messages, all in all great transaction would recommend !

product worked perfectly, super easy to install and very high quality components. 10/10 recommend

I was about to cut up and hack the wiring on my s14 to bypass the window amplifier and as I was looking for a step by step guide, I found Key'd Performance. Prior to ordering, I asked a couple of questions and Patrick got back to me briefly with answers.
When I got the product, the window still did not work, so I asked for a refund. They again reached out to me to diagnose the problem. After fidgeting with the system, I finally got it to work. For the price and time saved, I think it's a great company and I appreciate them being around and having solutions to the problems that these cars bring. I love my car and as long as companies like these are around, I will support them, just like they support me and my vehicle.
Great alternative to the OEM amplifier or hacking up the wiring. Now if they could only build a gas tank, rubber seals, plastic trim, etc... (I kid, but not really).
Keep up the great work guys!!!

So don’t get me wrong; I’m very appreciative for a quality product that’s plug and play, except on my harness the harness connector is female to female for the fog lights. But yes; I consider these a quality hand made product (I believe don’t quote me on that unless it’s right), but it could be a problem on my end for the bumper mounted fog, even though it’s OEM I hate to chop y’all’s connector off and make by own.

Plug and play and works like a charm! Finally being able to roll the window down genuinely restores the joy of driving. Thanks!

Plug in play.. easy as can be. 5 out of 5 for me.

These adapters are plug n play. No need to splice any wires! Quality is amazing. Can never go wrong with Key’d products. Patrick is also very helpful and answered some questions I had super quick!

It works✅

Very simple install, and works great! also beats cutting up stock wiring, looks really nice when it’s all installed too.

This kit is put together with high quality wire, fuse and relay holder, as well as simple to wire in and use. I would highly recommend this over hacking up your stock wiring!!
