Car Key Fob Not Working? 4 Next Steps

Key fobs are extremely convenient—until they stop working. If you own a car that doesn’t use a physical key, you may run into issues starting or getting into your vehicle if your key fob dies. Fortunately, there are some steps you can take that may help you diagnose the problem so you can get back on the road. In this article, we’ll go over four steps to follow if your key fob dies and some answers to frequently asked questions about key fobs.


Step 1: Check Your Key Fob’s Battery


Fixing your key fob might be as simple as replacing the fob’s battery. Typically, key fob batteries last between three to four years. If your fob isn’t working and the battery is older than three or four years, you probably need to replace the battery.


If you don’t know what battery to use when replacing the old one, your car’s manual should have directions on what type of battery you need to order for your fob. Once you have your new battery, open your fob with a small screwdriver, take out the old battery, put the new one in, and test it out.


If your key fob starts working, you’re good to go! If it still isn’t working, move on to the next step. 


Step 2: Reprogram the Key Fob


If your key fob isn’t working after you replace the battery, the programming could be at fault. While the exact steps may vary by model, you can find a general overview of how to program a car key fob below:

  • Enter Programming Mode: Get into your car and close all the doors. Put your key into the ignition and turn it so it’s in the “On” position without starting the engine. Typically, a vehicle will signal that its programming mode is on by making a chime or causing the doors to lock and unlock. Some cars will require you to go between “On” and “Off” several times before the programming mode starts, so check your vehicle’s owner’s manual to find out how many times you need to switch between the positions.
  • Press the Key Fob Button: With the vehicle in the “On” position and the programming mode started, press and hold the lock or unlock button on the fob for about 10 to 30 seconds. Your car may make a noise indicating that the fob has been programmed. 
  • Test the Fob: Test and see if your key fob is working. If it is, you’re all set!


Some vehicles require the fob to be programmed at the dealership or by a professional. If you own a vehicle with a fob you can’t program yourself, there isn’t really a workaround, and you’ll need to take it to a qualified professional.


Step 3: Check for Physical Damage


Like any piece of technology, key fobs can suffer from physical damage, which can break them. Give your fob a good once-over to make sure that there aren’t any cracks, the buttons are working, and it isn’t overly dirty. 

You can also open the key fob to inspect the circuit board if you’re comfortable doing so. Check for any signs of corrosion or visible damage on the circuits, as those can definitely cause problems. If your fob is damaged, you can see if it can be repaired at an auto shop, but you may need to replace it entirely.


Step 4: Seek Professional Help


If you still can’t get your fob to work, you should take it to your preferred auto shop. A technician can help you diagnose the problem and get your fob working again. If the mechanic can’t repair your key fob, the shop might be able to replace it for you.


Broken Key Fob FAQ


If you have additional questions about key fobs, review our answers to some of the most frequently asked questions when it comes to key fobs below:


1. How to Start Car With Dead Key Fob? 


If your car uses a keyless fob to start, knowing how to start a car with a dead key fob is essential to ensure you can still drive your vehicle. Most cars with keyless technology will start if you hold the “dead” fob up to the ignition button and try again. There may also be a small key in the fob for situations like this! If your key fob has one of those, look at the manual to find where you put the key into.


2. How to Unlock Car With Key Fob Inside? 


If you’ve accidentally locked your car with the fob inside, you can try to get the door open with a hanger or similar tool. If you don’t feel comfortable doing this, a locksmith or a roadside assistance provider should be able to get your car open for you in just a few minutes!


3. What Do I Do If I Got My Key Fob Wet?


If you dropped your key fob in water or got it wet, you can try to place it into a bag of rice to dry it out. Unfortunately, water will damage the chip inside the fob and may break it. Try drying the fob out for a bit in uncooked rice before you see if it works. If it’s still not functioning after drying it out, you may have to get a new fob.

It can be hard to keep up with all of the care that your vehicle needs. When a light comes on in your dashboard or a mechanic lets you know you are due for a new service, this can surface lots of questions. One common source of service confusion is the coolant flush. Thankfully, Chapel Hill Tire has you covered. Here is a look at the answers to all of your common coolant flush questions. Is it Really Necessary to Flush Coolant? Perhaps the most common question surrounding this service is, “Are coolant flushes really necessary?” The short answer is YES.  Your engine creates friction and heat in order to run properly. However, your engine is also made of metal pieces, which are malleable and vulnerable when heated. Extensive heat can cause a blown radiator, cracked gasket head, warped cylinder, and melted seals, among numerous other serious, dangerous, and expensive issues. To protect your engine from this heat, your radiator contains coolant that absorbs excess heat. Over time, your coolant will become worn out, burnt, and contaminated, causing it to lose its cooling properties. While you might not like hearing that you are due for an extra service, coolant flushes are necessary for a safe and healthy vehicle. Does Coolant Matter During Cold Weather? As we approach the fall and winter temperatures, you may become increasingly tempted to ignore coolant services. Does coolant matter in the cold weather? Yes—the friction and power of your engine generate heat year-round. While the summer temperatures certainly do intensify engine heating, coolant is still incredibly important in the winter. Additionally, coolant contains antifreeze, which will protect your engine from the dangers of cold temperatures. What is the Difference Between Coolant and Radiator Fluid? When reading your owner’s manual or various resources online, you might find “coolant” and “radiator fluid” terms used interchangeably. So are they the same thing? Yes! Radiator fluid and coolant are different names for the same material. You might also find it referenced as “radiator coolant,” which offers the best of both worlds. Is Coolant the Same as Antifreeze? Another common question that drivers ask—“Is antifreeze the same thing as coolant?” No, these two are not quite the same. Rather, coolant is the substance used to regulate the temperature of your engine. Antifreeze is the substance within your coolant that prevents freezing in the winter. You might find some sources that refer to coolant as providing cooling properties only; however, since the coolant often contains antifreeze, it has widely become a general term that encompasses both. How Frequently Are Coolant Flushes Needed? Generally speaking, a coolant flush is often needed every five years or 30,000-40,000 miles. However, coolant flush cadence can be impacted by your driving patterns, local climate, vehicle age, make, and model, as well as other factors. Consult your owner’s manual or a local professional for insight on whether or not you are due for a coolant flush. Additionally, you can look for signs of a needed coolant flush. These include a sweet maple syrup car smell and vehicle engine overheating. Take a closer look at these and other signs of a needed coolant flush here . How Much Does a Coolant Flush Cost? Many mechanics try to hide their prices from customers, which can create questions, confusion, and unpleasant surprises. While we cannot speak for the costs you will face at other mechanic shops, Chapel Hill Tire offers transparent pricing for every coolant flush and other services . Our coolant flushes cost $161.80, which includes the safe disposal of your contaminated fluid, professional-grade cleaning of your cooling system to remove rust and sludge, high-quality new coolant, coolant conditioner to keep it preserved, and a visual inspection of your entire cooling system.

Oil Change Prices Why do most mechanics and dealerships hide the costs of their services? You might be wondering if they will try to take advantage of your visit and overprice their services. Or perhaps they think that their oil changes are so expensive that displaying their service costs would deter customers from visiting the shop. At Chapel Hill Tire, we value our customers, which is why we display transparent pricing for all of our services. Here is everything you need to know about the actual price of oil changes. What Does an Oil Change Involve? One of the most common vehicle services—and arguably the most important for keeping your engine protected—is the oil change . This product keeps your engine lubricated so that it can function without harmful friction. Over time, your oil becomes filled with debris, making it less effective in providing proper protection for your engine. Your oil levels also become depleted as your engine burns through your oil supply. This is where an oil change comes in. Not only do you need to supply your vehicle with oil, but you also need to remove the old oil and replace the filter that prevents the harmful debris from entering your engine. If you partner with an outstanding oil change expert, you will also receive routine vehicle checks included in the price of your oil change. On average, you need an oil change every 3,000 miles or every six months , whichever comes sooner. Maintaining regular oil change services will keep your vehicle protected and prevent costly engine damage from occurring. How Much Does an Oil Change Actually Cost? Every mechanic has to price their oil changes in a way that helps keep business open. However, you want to ensure that this number does not take advantage of your visit. Here is how much an oil change actually costs your mechanic: Oil Costs : Perhaps the most obvious expense, the mechanic will pay for several quarts of oil to fill your reserve. There are multiple different types of oil that vary in thickness, which can affect your oil change costs. If you take a look at your oil cap, it will tell you which type of oil your engine requires. Labor Cost : Here, you pay for the years of experience and the professional care provided by your oil change technician. You also reap the convenience of having an expert take care of your vehicle. Filter Cost : Your oil filter keeps contaminants out of your engine. These contaminants can wear away at your filter over time, which is why you require regular filter replacements. The cost of your filter may vary slightly depending on your vehicle make, model, trim, and year. Disposing of Used Oil Cost : Part of the hassle of an at-home oil change is navigating the disposal of the old, messy, and contaminated oil. An expert mechanic has the resources and an established process to ethically dispose of old oil. Collectively, what you pay will reflect the cost of the oil change for your mechanic. Even with all of these offerings, oil changes are often reasonably priced—usually running between $40-$70. You can also find oil change coupons to help offset the cost of this service. Transparent Oil Change Prices You won’t find hidden costs here at Chapel Hill Tire. Instead, we keep all of our prices clear and transparent on our services page . The only variance possible in this price is if your vehicle requires a filter or oil that is non-standard or higher in cost. This price includes five quarts of oil, an oil filter change, an air filter check, a fluid levels check, an inspection of your belts and hoses, and a tire air pressure check.
