How To Turn On Car If Key Fob Is Dead

If your car key fob battery dies, getting your vehicle started can feel daunting, but don’t worry—there are workarounds that can get you back on the road. This guide covers tips to start your car without a functioning fob and addresses common questions like “will a dead battery in a key fob cause the car not to start?” and “how to start a car without a key fob.” Here’s what to know, especially if you’re navigating Ottawa streets and might need a hand from a local car locksmith.

1. Identify the Issue

Before troubleshooting, check whether your key fob battery is indeed the problem. If the car fob’s response has been weak or inconsistent recently, chances are the battery is low. Some cars will display a “key battery low” warning, especially for brands like Toyota and BMW, which can help you catch the issue early. If that’s the case, you’ll need a quick replacement battery for your car key. Search “car key battery near me” or “where to buy car key battery” for the nearest stores in Ottawa that carry key fob batteries, typically a CR2032 battery.

2. Use the Manual Key Inside Your Fob

Most modern key fobs, from brands like Hyundai, Honda, Nissan and Mazda, contain a hidden physical key. Here’s how to access it:

  • Locate and Open the Key Fob: Find the small latch or button on the side of your fob. Pressing or sliding this button usually releases the hidden manual key. Need help? A quick search on “how to open car key fob” will provide detailed steps.
  • Unlock the Car: Use the manual key to unlock the driver’s side door manually. This will override any battery issues in the fob.

Even without a working fob, this manual key will let you access the car. Remember to store it somewhere accessible, so you’re prepared if the fob battery dies unexpectedly.

3. Start a Push-Button Car with a Dead Key Fob

For push-button cars, the process varies slightly, but there’s often an easy solution:

  • Push the Key Fob Against the Start Button: Many push-button start systems have a backup feature that allows the car to detect the fob even if the battery is low. Press and hold the fob near the start button or the steering column. This should allow the car to detect the signal and start.
  • Use a Key Slot: Some vehicles, especially older models, have a manual key slot. For example, BMWs may have a manual key slot, while Mazda models may have fob tricks that enable you to use a low-battery fob. This slot is typically located near the steering wheel or center console. Insert the fob into this slot, and the car should start.

If these methods don’t work, Ottawa drivers can reach out to our car locksmith service at (613) 663-1033 for expert assistance in troubleshooting, reprogramming, or replacing the fob battery.

4. Starting the Car Without the Fob

If you don’t have the fob on hand, alternative methods vary depending on the car’s make and model. Some general strategies include:

  • Use a Keyless Start App: Some vehicles, like specific Ford or Hyundai models, have apps that allow remote access and starting, provided your phone is synced with the car.
  • Backup Fob: If you have a spare fob with a functional battery, it’s a simple solution to your problem. Keeping a backup fob is especially helpful in emergencies and is a good practice for peace of mind.

5. Replacing the Key Fob Battery

If your key fob battery is indeed the issue, replacing it is straightforward and can be done with basic tools. Here’s how:

  • Remove the Back of the Fob: Use a small screwdriver to pry open the fob. Make sure to handle it carefully to avoid damaging the internal components.
  • Replace the Battery: Once open, locate the battery compartment and swap out the old battery with a new one. The battery type is usually listed inside the fob; CR2032 is common.
  • Test the Fob: After replacing the battery, test the fob’s functions to ensure it’s working. For Ottawa locals, many stores stock these small batteries, so a quick search for “battery for car key fob” will help you find a nearby option.

7. Pro Tips for Long-Term Fob Maintenance

Maintaining your key fob can help prevent sudden malfunctions. Here are some tips to extend the lifespan of your car’s remote key fob:

  • Replace Batteries Regularly: Fob batteries last one to two years on average. Proactively replacing the battery when it shows signs of slowing down will help you avoid getting stuck unexpectedly.
  • Store the Fob Carefully: Avoid placing the fob in areas with high moisture, extreme temperatures, or electronic interference, which can affect its performance over time.
  • Use a Fob Tester: Fob testers are available to check the strength of the signal from your key fob. A weak signal often indicates the need for a new battery.
