In this blog post, we'll go over some common reasons why your key fob may not be working after a battery change, and what you can do to fix the problem.

Key Fob Not Working After Battery Change - What you can do

Check the Battery

The first step to fixing a key fob that isn't working after a battery change is to check the battery. Make sure the battery is the correct type and properly inserted. If the battery is the correct type and properly inserted, but the key fob still isn't working, try replacing the battery with a new one to ensure that the battery is not faulty.

Check for Electrical Interference

If the battery is not the issue, check for potential sources of electrical interference. Move away from any potential sources of interference, such as wireless routers or cell phones, and try using your key fob again.

Reprogram the Key Fob

If the battery and electrical interference are not the problem, try reprogramming your key fob. Reprogramming your key fob can reset the communication between the key fob and your car's locking system, which can sometimes resolve the issue. Consult your car's owner's manual or contact a professional for instructions on how to reprogram your key fob.

Replace the Key Fob

If none of the above solutions work, it may be time to replace your key fob. If your key fob is damaged or malfunctioning, it may not work even with a new battery. Contact a professional to order a replacement key fob and have it programmed to work with your car's locking system.

If you have determined that you need to replace your key fob, the next step is to find a professional who can help you do so. Here are some tips on how to find a professional to replace your key fob:

Ask Help To An Experience Auto Locksmith

If your key fob is not working after a battery change, one of the first things to consider is seeking assistance from an automotive locksmith. Automotive locksmiths are experienced in working with car keys and key fobs, and can often diagnose and resolve issues related to key fob functionality.

When you contact an automotive locksmith, they may first check the battery to ensure it has been installed correctly and is fully charged. If the battery is not the issue, they may then move on to re-syncing the key fob to the car, as this can sometimes be necessary after a battery change.

If these steps do not resolve the issue, an automotive locksmith can then use specialized equipment to diagnose the problem and make any necessary repairs or replacements. For example, they may need to replace the key fob entirely, or reprogram it to ensure it is communicating correctly with the car.

Contact Your Car Dealer

The first place to start when looking for a professional to replace your key fob is your car dealer. They will have the expertise and knowledge to help you order the correct replacement key fob and program it to work with your car's locking system. However, keep in mind that going through your dealer may be more expensive than other options.

Ask for Recommendations

Ask friends, family, and coworkers if they have any recommendations for a professional who can replace your key fob. Personal recommendations can be especially helpful in finding a reliable and trustworthy professional.

Check Credentials

Before choosing a professional to replace your key fob, check their credentials. Look for certifications or licenses that indicate they have the knowledge and skills necessary to replace your key fob correctly. You may also want to check if the professional is insured, in case anything goes wrong during the replacement process.

Compare Prices

Finally, it's a good idea to compare prices from different professionals to make sure you're getting a fair price. However, keep in mind that the cheapest option may not always be the best option. Look for a professional who offers a reasonable price and who has the experience and knowledge to replace your key fob correctly.
