Is your 2007 Lexus GS350 key fob starting to feel unresponsive? You might be facing the common issue of a dead or dying battery. Fortunately, replacing the battery in your Lexus GS350 key fob is a straightforward task you can easily handle yourself, saving you time and money. This guide will walk you through the simple steps to replace your key fob battery and get you back on the road with a functional remote.
The good news is that Lexus GS350 key fobs typically use widely available and inexpensive batteries: the CR1632 and CR2032. These batteries are common for key fobs and other small electronic devices, meaning you can find them at most drugstores, electronics stores, and online retailers for just a few dollars.
To replace your 2007 Lexus Gs350 Key Fob Battery, you’ll only need a couple of simple tools:
- A new CR1632 or CR2032 battery (check your owner’s manual or the old battery for the exact type)
- A small flathead screwdriver or your Lexus GS350’s mechanical key
Here’s how to replace the battery in your 2007 Lexus GS350 key fob:
-
Prepare to Open the Fob: Locate the emergency key slot on your key fob. This is often on the bottom or back of the fob.
-
Release the Emergency Key: If your fob has a release button or latch, press it to detach the emergency key. For some models, you may need to slide a small switch. Remove the mechanical key from the key fob.
-
Open the Key Fob Casing: Once the mechanical key is removed, you’ll see a small notch or slot where the key was. Insert the emergency key or a small flathead screwdriver into this slot. Gently twist or pry to separate the two halves of the key fob casing. Be careful not to apply excessive force, as you could damage the plastic casing.
-
Access the Battery: With the case open, carefully lift the circuit board to reveal the battery compartment. Note the orientation of the old battery – specifically which side is facing up – so you insert the new one correctly.
-
Remove the Old Battery: Gently pry out the old battery. You can use your fingertip or the small flathead screwdriver, being careful not to damage the surrounding components.
-
Insert the New Battery: Place the new CR1632 or CR2032 battery into the compartment, ensuring the correct orientation (positive side up, usually marked with a “+”). Push down gently to secure it in place.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly together until they snap back into place. Ensure the case is fully closed and secure.
-
Test Your Key Fob: Press the buttons on your key fob to test its functionality. The doors should lock and unlock, and the panic button should work if your fob is equipped with one. If it’s still not working, double-check the battery orientation and ensure the battery contacts are clean and making good contact.

- Remote Heads: Keys directly attached to the remote, not retractable.
- Fobik Keys: Remotes with a separate, hidden mechanical key.
