5 Reasons Why Your Car Key Isn’t Working

June 8, 2023

Isn’t it frustrating when you’re about to head to work or take your kids to school and suddenly your car key isn’t functioning? Everyone can agree that car keys are a crucial part of operating a car and if they’re not working it can put our whole day on hold. If your car key isn’t working it’s critical to figure out the cause, so you can come up with a reasonable solution. Keep in mind, that if you are uncertain how to handle a situation, it’s advised to contact a locksmith instead of taking the risk of causing further damage to your car. At Brothers Locksmith, we understand how stressful it is when your car key won’t work, so we’ve provided five reasons why we think your car keys may not be working.

 

Your Key is Damaged

Your car key may not be functioning because your car key could be damaged! Your key doesn’t have to be broken in order to be damaged. A lot of people don’t realize that car keys can become damaged and worn through everyday use. When you constantly use your car keys, the grooves can be morphed causing the key to no longer work. 

 

Your Lock is Damaged

Keys aren’t the only things that can be damaged. If your key isn’t impaired, there’s a chance that the locks. If you’re driving a newer car, it’s likely that you have a key fob, and don’t have to worry about this issue. However, this can be a common problem for older models due to exterior forces or environmental changes. There could be many reasons why your car lock is not working correctly. It may not be effectively operating because of wear and tear, dirty locks, a recent accident, or a car break-in. The best solution is to call a locksmith—you may need a car lock replacement.

 

Malfunctioning Ignition Cylinder

Your car key isn’t just responsible for opening your car doors and trunk, but it also can start your car. In some cases, you may not be having issues opening your car doors, instead you’re having issues turning on your car due to a malfunctioning ignition cylinder. This can be caused by an accident, or theft, or can simply happen over time. The ignition may need to be fixed or replaced with a new cylinder. An automotive locksmith has the ability to diagnose and resolve your ignition issues by repairing or replacing faulty ignition switches. 

 

Drained Key Fob Batteries 

If you notice that when you are clicking buttons on your key fob,  your car is not being responsive, it is likely that your batteries are dead. This frequent problem has a relatively straightforward solution. Batteries tend to run out after a certain period of time and all you need to do is replace them! 

 

The Key Wasn’t Programmed Properly

Regular keys certainly won’t have a programming issue, however car key fobs often do. Newer cars usually use transponder keys, or sometimes known as chip keys. A transponder key has a chip implanted in it that communicates with your vehicle, and until the vehicle receives the right message from the transponder, the car will not start. It’s possible that your transponder key has not programmed correctly. An automotive locksmith can diagnose the problem and fix it.  

 

What Should You Do When Your Car Keys Aren’t Working?

When your car keys aren’t working and you’re not sure what the issue is and how to fix it, we recommend that you immediately call Brothers Locksmith. If you’re in a rush to be someplace, you don’t want to be even later than you already are. Instead of wasting even more time trying to diagnose the issue and come up with a solution by yourself, contact us and we’ll gladly come to you quickly.

It happens to the best of us. You're running late, juggling groceries or half-awake on your way to work, and before you realize it—the door clicks shut, and your keys are inside. Getting locked out isn’t just inconvenient—it’s stressful, time-consuming, and sometimes downright expensive. The good news? It’s also highly preventable. In this comprehensive guide, we’ll walk you through smart, real-world strategies to avoid getting locked out again—whether it’s your home, office, or car. These expert prevention tips come straight from the locksmith trenches, and they’re easy to apply, whether you’re forgetful, busy, or just tired of relying on emergency locksmiths. Understand Why Lockouts Happen in the First Place Before solving the problem, we need to understand it. Lockouts typically happen due to: Forgetting or misplacing keys Keys getting locked inside a car or home Doors that auto-lock Broken or worn-out keys Malfunctioning locks or key fobs Most of these are preventable with simple habits, upgrades, or tools. Let’s break them down one by one. Step 1: Create a Key Routine That You Can Stick To One of the most powerful prevention tools? Muscle memory. Create a ritual around your keys—something small and repeatable every time you leave your home, office, or car. For example: Always touch your keys before shutting the door Say “Phone, Wallet, Keys” as a mental checklist Place a reminder near the door (“Do you have your keys?” sign) These tiny behaviors train your brain to check for keys automatically—no effort required after a while. Step 2: Store a Spare Key (But Not Under the Mat!) A spare key is your best backup—but only if it’s stored smartly. Avoid outdated hiding spots like under the doormat, flowerpot, or inside the mailbox. These are the first places burglars check. Instead: Leave a spare with a trusted neighbor or friend Install a secure, weatherproof key lock box with a code Store it in your wallet or bag if it doesn’t interfere with routine And whatever you do, never label your key with your name or address. If it’s lost, your home could be at risk. More on this in our guide: Why You Should Never Hide a Spare Key Under the Mat Step 3: Duplicate and Distribute—Strategically Don’t rely on one key to rule your world. Instead, get professional duplicates made and keep them where you’re most likely to need them. Some smart storage ideas include: One in your car (but hidden securely) One in your gym bag or laptop case One at your workplace One with your dog walker, babysitter, or close family member Just make sure you trust whoever has access—and always update your key plan after roommates or tenants move out. Step 4: Go Keyless With Smart Locks If lockouts are a recurring issue, it might be time to ditch the keys altogether. Smart locks allow you to unlock doors using: Keypads (PIN codes) Smartphones Fingerprint access Bluetooth or Wi-Fi apps Some models even let you generate temporary codes for guests or service workers—so you don’t have to hide a key or hand out spares. Check out How to Upgrade to a Smart Lock Without Changing Your Door for a step-by-step breakdown of modern options that don’t require full door replacements. Step 5: Regularly Inspect Your Locks and Keys Sometimes, it’s not forgetfulness—it’s a failing lock or worn-out key that locks you out. Signs your key or lock may be due for a replacement: Your key feels loose or stiff in the lock You have to jiggle it to get it to work Your key is cracked, bent, or visibly worn You hear clicking, scraping, or feel resistance when turning A quick inspection once a month can catch small issues before they leave you stranded on the porch.

Step 6: Have a Go-To Locksmith on Speed Dial In case prevention fails (because life happens), don’t waste time Googling at 2AM when you're locked out. Instead: Research a local, licensed locksmith now Save their number in your phone as “Emergency Locksmith” Confirm they offer 24/7 lockout assistance Check their reviews, verify their licensing, and build a relationship with them before you need them. Our guide on How to Find a Licensed and Trustworthy Locksmith Near You walks you through exactly how. Step 7: Use a Smart Reminder or Tracker If you’re forgetful (hey, we’ve all been there), tech can help: Use a Tile or Apple AirTag on your keychain to track misplaced keys Set location-based reminders on your phone to check for keys before leaving Use apps like “Alarmy” to set a custom checklist for leaving the house These small hacks go a long way in building dependable habits. Bonus Tip: Re-Key After a Lockout (If Needed) If your lockout was caused by lost keys, it’s safer to rekey or replace the locks afterward. Why? Because if someone finds your keys and knows where you live, your home is no longer secure. Not sure what’s best? We break it down in Rekey vs Replace Locks: Which Is Better for New Homeowners? Final Thoughts: Lockouts Are Avoidable With the Right Systems A lockout doesn’t have to be part of your weekly routine. With a few simple changes—like key duplication, smart storage, tech upgrades, and routine maintenance—you can make sure that panic moment at the front door never happens again. It’s not about being perfect. It’s about being prepared. If you ever do get locked out again, don’t panic. Just call your trusted locksmith and take it as a reminder to refine your prevention system. You’ve got this—and your keys.
