Step-by-Step Guide to Replacing Your 2006 Lexus IS250 Key Fob Battery
Replacing the battery in your 2006 Lexus IS250 key fob is a quick task that requires minimal tools. The opening procedure can vary slightly depending on whether you have a newer or older style key fob. Here’s how to do it:
Opening Your Lexus IS250 Key Fob
For some older Lexus IS250 models, you’ll find a small notch on the key fob case. To open this type, you’ll need a thin, flat object like a small flathead screwdriver. Carefully insert the screwdriver into the notch and gently pry the case open. Be cautious not to apply excessive force to avoid damaging the plastic casing.
For newer 2006 Lexus IS250 key fobs, the process is even simpler. Locate the hidden key within your key fob and remove it. This will often reveal a designated slot where the key was housed. Insert the metal key into this slot. This action is designed to release the key fob casing, allowing you to easily separate the two halves.
Battery Access and Replacement
Once you have successfully opened the key fob casing, you will see the internal components, including the circuit board and the battery. Gently lift the circuit board to gain clear access to the battery compartment underneath. Before removing the old battery, take a moment to observe its orientation – note which side is facing up and how it sits in the compartment. This will be helpful when installing the new battery.
Now, carefully remove the old battery. Install the new CR1632 or CR2032 battery, ensuring it is placed in the correct orientation as you noted earlier. The battery should fit snugly into the compartment.
Testing Your Key Fob
After replacing the battery, carefully close the key fob case, ensuring both halves snap back together securely. Take a moment to test your key fob’s functionality. Press the buttons to lock, unlock, or activate other functions of your Lexus IS250. If everything works as expected, you’ve successfully replaced your key fob battery!
If your key fob still doesn’t work, double-check that the battery is correctly installed and that the battery contacts are clean and making good contact with the battery. Sometimes, a slight adjustment is all that’s needed.
Exploring Key Fob Types
While focusing on battery replacement, it’s interesting to know that key fobs come in various designs. Here are five common types:
- Standard Remotes: Basic remotes with standard lock/unlock functions.
- Flip Keys: Keys attached to the remote that flip out, similar to a switchblade.
- Remote Heads: Keys integrated into the remote that are fixed and don’t retract.
- Fobik Keys: Remotes with a separate, hidden key blade that isn’t directly connected to the fob.
