If I change the battery, do I need to reprogram my key fob?
A remote key fob needs to be associated with your vehicle particularly in order to be secure.
This stops people who drive the same make and model of automobile as you from using their remote to access your car. You’ll need to reprogram the fob if changing the batteries has erased this connection or if it was somehow disrupted in order for it to once again recognize your automobile.
Standard programming sequence
Your key fob can typically be reconfigured by following this typical procedure:
Instead of starting and then returning to the locked position, turn the key into the run position. Repeat this multiple times.
You’ll typically hear a chime or other sound when you’ve cycled the key enough times. At that point, you can push the lock or unlock button on your key fob to hear another chime.
What happens if the battery in your keyless remote runs out?
This issue has been foreseen by automakers ever since the key fob was created. Nothing will happen if your key fob dies while you’re driving. Simply because the key fob is a locking and starting device only, the automobile will continue to run. The key fob has no influence over the ignition or engine once the automobile is moving.
Even though you’ll need to go to a general store or pharmacy to get the battery, replacing the battery in your key fob simply takes a few minutes if you’re pressed for time.

Hot & Cold
Many people are unaware that hot weather may be just as detrimental to a car battery as cold weather. Extreme weather depletes the batteries’ energy, which increases the likelihood that the engine won’t start the next time you try to start it.
I believe that extreme cold is more likely to destroy a car battery. This is because the engine oil has a thicker viscosity at lower temperatures, which makes the engine work more difficultly.

Corroded battery terminals may be a sign that you need to purchase a new battery. However, there are other potential causes for the corrosion of your terminals.
