Car Key Isn't Working? Common Problems and Solutions

You’re raring to hit the road, but when you try to unlock your car, the engine doesn’t start — nothing happens.

From a dead battery or a broken key to an issue with your automobile’s ignition system, knowing the general causes can save you time and headache.

Dead Battery in Key Fob

The key fob having a dead battery can be a surprising obstacle, especially if you are in a rush. Sometimes the simplest of problems are the most irritating. When your car won’t unlock or start, the first thing you should check is the key fob battery. This is such a basic troubleshooting step that most people ignore, often thinking that their fob is even broken and not considering it just needs a quick battery change. The majority of key fobs use standard coin batteries, inexpensive and easy to replace, a quick fix that can save you time and money.

But if battery replacement is not solving the problem, then it might be indicative of an even bigger issue like a damaged circuit board or faulty internal parts. So call a pro locksmith or your dealership to help you on those cases. Also, many newer cars have alternative ways to start your car if you lose your remote that don’t require busting out a skill saw to unlock it; if you need the information to access these features, check your owner’s manual. With a little diligence about the upkeep of your key fob, you can prevent the aggravation that comes from being locked out of your car and ensure that you don’t have to make changes to your daily schedule.

Damaged Key Blade or Remote

Getting locked out of your vehicle due to a broken key blade or remote can be one of the frustrating blocks in your life that leads to feeling helpless. The most common reasons why a key might stop working range from normal wear and tear from daily use, to accidental damage (like bending the blade or dropping the remote). Even aesthetic flaws can impact performance — the internal circuits that are disrupted by a casing crack.

If you think that your key is the issue, you should look at the key itself closely. Check for visible signs of damage, but don’t rule out the potential for internal problems. For remotes, it may simply need a new battery, while a locksmith can repair or replace a damaged blade without replacing the entire key assembly. When you know that these are actually complex devices developed to communicate with your car’s security system, you can appreciate their intricacy and why taking care of them is key.

And in our hyperconnected world where electronic signals permeate everything — from Wi-Fi routers and smartphones to cars parked nearby — plenty of signals can interfere with communication between your key fob and the car. Ever parked near a busy shopping mall, shared parking lot, or crowded area, then noticed your key fob acting wonky? Out Of Silence, this is a signal collision, where too many devices scramble for your attention.

For fixing this, commute to some other place where Wi-Fi interference is minimal. You may be surprised at how much functionality can be restored just by repositioning yourself. Also, look for some new devices or appliances installed in your home or garage that might be producing the electromagnetic interference. Even something as benign as LED lighting can sometimes make it hard to work. Knowing these dynamics of interference will enable you to take preventive action, so your key fob always works when you need it to once you get in your car.

How to Perform Preventive Maintenance?

Another aspect is preventive maintenance, which is often one of the most overlooked, but in reality can be a huge game changer in ensuring your car key and ignition system works in tip top shape. But one important thing to keep in mind is that you should check your key fob regularly for any signs of wear and tear, like a cracked button or a battery that is no longer functioning as it should. Most drivers take the battery all the way until it dies then they be getting locked out instead of replacing it on time after the battery has run down to the point of being flat to avoid inconveniences. Invest in a battery replacement kit, and you’ll be able to complete this small but vital job on your own.

Also keep your car’s ignition system clean and debris-free. Over time, dirt and grime can accumulate and create poor connections that keep your key from working correctly. You will be amazed at just how still that little soft protection can be if you give it a little clean and/or use compressed air. Pay attention to what’s going on with your vehicle’s electronics; if you notice odd behavior from the power locks or dashboard lights, it might be a good idea to check in with a professional.
