Josh from JP Auto & Fleet Services is going to teach you how to start a car without a key. Now, let’s be clear, this is not to be used for nefarious purposes and stealing cars.

This technique is to be used when you are stuck and in a bit of trouble as you will see in this video. It is also used for diagnostic purposes such as those shown in the video as well.

Let’s get down to business. I received a call from a customer of mine, his engine light started blinking on his car, flashing going crazy while has was on the highway. Luckily, he was able to get off the highway because his car died.

He actually had to get off the highway and got to a store that was close by to me so I went to help him out. The Kia van wouldn’t crank over but I was able to get it started and back to my shop.

The battery in the van was completely dead and the starter wouldn’t crank at all. I’m going to share with you exactly how I was able to get the van started and over to my shop in Lake Dallas, TX.

Diagnosing the inside the car first, the lights are showing on the dashboard with the keys in the ignition but no “click-click” when turning the key. Now, I’m going to look under the hood.

I knew the battery was toast so I had brought a new battery to the store where he pulled over and installed that prior to getting it started. I needed good voltage to be able to do all the diagnostic testing.

I took my power probe, which can send power and ground to any accessory, and tested the battery I installed. It tested at 12.3 volts and that is enough battery voltage to crank this vehicle over.

The van should have been at least turning over and cranking if not starting so I went to the next stage. Before I get into the starter, I’m going to start with the starter reply.

One way to check the starter without getting into it fully is to send voltage down to it with the power probe. By sending voltage directly to the starter via the starter reply it cranked right up and started.

What this tells us is we don’t have a bad starter. The next stage was to test the alternator. Using the power probe again, the alternator was at 12.1 volts which is below what is needed to start a vehicle. The acceptable range for an alternator is 13.3 – 14.8 volts.

This brings us now to one of two things, we either have a bad alternator or an electrical issue somewhere that is not allowing the battery to charge properly. My bet on this is that we have an electrical issue.

Several indications show me that this is a rust bucket vehicle. I came across a break in the wire on the fuel injector. I also came across several places with open copper wire and this can result in short circuits.

Important note: this video is for diagnostic purposes only, we are not trying to steal cars here. However, a lot of times, this particular technique showing how to start a car without a key or how to hotwire a car is needed to rule out a bad starter, a faulty ignition, or troubleshoot an alternator battery charging issue.
