Car keys are one of those pieces of technology that we take for granted. We don’t really think about how they work, or what can go wrong when they don’t work. In this blog post, we will explore how to change a car key battery. We will also provide some tips on how to prevent car key theft in the first place. By understanding how car keys work and what happens when they don’t, you can keep your car safe and your valuables safe too.
What to do if your car won’t start
If you’ve tried all the usual car starting troubleshooting methods and your car still won’t start, it might be time to change the battery. Changing the battery in a car is usually a fairly straightforward process, but there are a few things to keep in mind.
First, if your car has a keyless entry system, make sure you have the correct key for your car. Otherwise, you’ll need to get a new key cut. (If you don’t have a keyless entry system, you can usually just remove the battery cover and replace the battery.)
Second, check all of the fuses in your car. A blown fuse can cause your car to not start no matter what else is wrong with it.
Third, make sure that all of your electrical connections are tight – especially the ones that run under the dashboard or between the engine and gearbox. If any of these connections are loose or corroded, they can cause problems with your car’s electrical systems.
Finally, if none of these steps help get your car started, it might be time to take it into a mechanic.

What tools you need
If your car key battery is losing power, there are a few things you can do to get it started. You’ll need a Phillips head screwdriver, a voltmeter, and a cable clip. Start by disconnecting the negative battery cable from the car. Next, connect the positive battery cable to the car and use the voltmeter to measure the voltage. If it’s below 12 volts, you’ll need to replace the battery. If it’s between 12 and 13 volts, you can wait until your next service interval to replace the battery. If it’s above 13 volts, you’ll need to replace the entire key fob.
