  1. Lost or Stolen Keys: If your car keys are lost or stolen, rekeying the locks becomes a crucial security measure.
  2. Purchasing a Used Car: When acquiring a used car, it's a good practice to rekey the locks to ensure you have sole access.
  3. Security Concerns: If you suspect unauthorized access or fear that someone might have a copy of your key, rekeying enhances security.
  4. Worn or Damaged Locks: Over time, locks can wear out or sustain damage, making rekeying a practical solution.

A key fob is a small yet powerful device that provides remote access to your car. But if you find yourself constantly replacing its battery, it’s not just an inconvenience—it could signal an underlying issue. Let’s explore why your key fob battery might be draining faster than it should and what you can do about it. How to Open a Car With Dead Battery and Locked Doors 1. Constant Signal Communication Key fobs use radio frequency (RF) signals to communicate with your vehicle. Some models are designed to stay in continuous communication with your car, especially those with keyless entry or push-button start systems. This “always-on” signal drains the battery over time. Tip: Keep your key fob away from your car when not in use. If it stays close—like in a nearby hallway or garage—the fob and car may constantly "ping" each other, draining the battery faster. 2. Faulty Buttons or Internal Damage Sticky or worn-out buttons can remain slightly pressed, even when the key fob appears untouched. This constant pressure can force the device to send signals nonstop, causing rapid battery drain. What to do: Check for any stuck buttons or visible cracks. If the fob has been dropped or exposed to moisture, internal damage might be the culprit. Replacing the casing or getting it inspected can help. 3. Low-Quality Replacement Batteries Not all batteries are created equal. If you recently replaced the battery and it’s still draining quickly, a cheap or expired cell might be the reason. Solution: Always choose high-quality, brand-name coin cell batteries. Check the expiration date before buying, even if the packaging is sealed. 4. Extreme Temperature Exposure Hot summers or freezing winters can impact the performance of lithium coin batteries. If you leave your key fob in your car, especially in the cupholder or dashboard, it may be exposed to extreme temperatures that drain the battery. Fix: Store your key fob indoors when you’re not driving. Avoid leaving it in the car for extended periods. 5. Old Age of the Key Fob If your key fob is several years old, its internal components—especially the circuit board—may begin to wear down. Aging electronics are less efficient, which can lead to faster battery consumption. Tip: If your key fob is older than 5-7 years and constantly draining batteries, it may be time for a replacement or reprogramming. 6. Interference from Other Electronic Devices In some cases, nearby electronic signals—like those from Wi-Fi routers, smart home devices, or even other key fobs—can interfere with the fob’s signal. This interference can cause the fob to work harder to maintain a connection, draining the battery faster. Suggestion: Try storing your fob in a different location away from these devices, especially overnight. Can You Program a Transponder Key Without a Locksmith?  Final Thoughts A fast-draining key fob battery is more than just a minor nuisance—it could be a symptom of a deeper issue. Whether it’s excessive communication, faulty buttons, or environmental exposure, identifying the cause can help you fix it for good. If the problem persists even after battery replacement, it’s best to consult an automotive locksmit h or dealership for a full key fob diagnosis.
