I’ve noticed that many people are interested in engine start buttons and the such. These days you can find cheap remote start/push button start modules on Ebay and Aliexpress. But, are they worth buying and the trouble of installing? I’ve purchased a cheap PKE(Passive Key-less Entry) system for $60(USD) from Ebay to find out.

These days everyone has a device that is charged using a USB port. Sometimes those devices run low on power before the day is through. I thought any passenger who rides in my car would appreciate being able to plug their devices in and charge them. Yes, I could use a charger the plugs into the 12 volt power outlet, but my car only has one in the front, which is not ideal for any passengers in the back seat.

A lot of people have been telling me that I should add RFID to my engine start button project. That’s exactly what I did. I’m using an Arduino Nano connected to a RC522 RFID reader/writer. When the Nano recognizes a scanned RFID tag, it sends a code via serial to the ATMega328 that controls the ignition/accessories/starter motor. When the ATMega328 receives the code, it enables the engine start functionality. If no RFID tag is scanned or if an incorrect tag is scanned, pressing the engine start button will not start the engine.
Here are some photos that I took while everything is wired-up in my car.
Here’s the best low-cost way to put a fully functional engine start button in your car! Absolutely no key needed to start your car! Just press the button and go!
You may have seen others put engine start buttons in their cars, but they still had to use a key! It’s like, “really, guys? You’re adding a step to starting your car“! You definitely don’t want to be like those idiots. You, you’re much smarter than those hook-it-straight-to-the-starter guys. You know there’s gotta be a better way… and there is!

This is what I did to power the Arduino which I used in my engine start button project. It’s a simple and cheap way to power an Arduino in a car. This will requires some basic soldering skills.
But a simple USB charger – the kind that plugs into your car’s power outlet. They usually cost ~$2-5(USD). You can probably find them at most convenience stores, or maybe a box store of your choice.
The first place that I was going to install the button was in the larger hole cover that covers the hole in the dash where accessory switches go, but were not used. However, I found a better location while solving the steering lock issue. The key cylinder also operates the steering lock, but if I’m not going to use the key to start the car, the steering lock just inconveniences me. I had to remove it.
After adding the relay module and start button, as well as making some changes to the code, I wired my test circuit up to CRX to see if it could actually work. Video below…
