How To Open Lexus Key Fob Without Title
Losing your Lexus key fob can be a stressful experience. Not only is it a hassle to replace, but it can also be expensive. If you’ve lost your key fob, don’t panic. There are a few things you can do to open your Lexus without a key fob.
First, try to find your key fob. Retrace your steps and look in places where you might have dropped it. If you can’t find it, you can try to use a spare key. If you don’t have a spare key, you can call a locksmith. A locksmith can help you open your Lexus and make a new key fob.
Locating the Key Release Button
Identifying the key release button on your Lexus key fob is crucial. Various Lexus models have subtly different key fob designs, and the release button’s placement can vary. However, here are some general guidelines to help you locate it:
Older Lexus Key Fobs (Pre-2015)
For pre-2015 Lexus models, the key release button is often found on the side of the key fob, near the top. Look for a small, rectangular button that may have an arrow or unlock symbol engraved on it. Pressing this button will cause the physical key to pop out of the fob.
Newer Lexus Key Fobs (2015 and Onward)
Newer Lexus key fobs typically have the key release button located on the back of the fob. Again, it’s a small, rectangular button, often with an arrow or unlock symbol. Pressing this button will release the physical key, which will slide out of the bottom of the fob.
Key Fobs with Integrated Keys
Some Lexus models have key fobs with integrated keys, meaning the physical key is permanently attached to the fob. For these fobs, there is no separate key release button. Instead, you need to squeeze the sides of the fob together to release the key.

Using a Flathead Screwdriver to Pry Open the Key Fob
This method involves using a flathead screwdriver to carefully pry open the key fob. It’s a more delicate approach, but it can be effective if done cautiously.
Step 1: Gather Your Tools
You’ll need a flathead screwdriver (size 1.5mm or smaller is recommended) and a small, flat object like a butter knife or credit card.
Step 2: Locate the Pry Point
On most Lexus key fobs, there’s a small notch or seam along the edge where you can insert the screwdriver. Look for a spot that’s not too close to any buttons or circuits.
Step 3: Pry Open the Case
Carefully insert the screwdriver into the notch and gently pry it open. Be extremely careful not to damage any delicate components inside.
Step 4: Separate the Halves
Once the case is open, use the flat object to gently separate the front and back halves of the key fob. Inside, you’ll find the battery, circuit board, and other key components.
Step 5: Replace the Battery or Fix the Malfunction
If you’re replacing the battery, simply remove the old one and insert the new one. If you’re fixing a malfunction, carefully inspect the circuit board and components for any visible issues.
Step 6: Reassemble the Key Fob
Once you’ve replaced the battery or fixed the issue, reassemble the key fob by aligning the front and back halves and gently pressing them together. Ensure that the case is securely closed before using the key fob.
Removing the Key Blade
The key blade is the metal part of the key fob that you insert into the ignition of your car. If your key blade needs to be replaced, you can do so by following these steps:
- Use a small screwdriver or other sharp object to pry the back of the key fob apart. Be careful not to damage the fob.
- Once the back of the fob is removed, you will see the key blade. Grip the blade firmly and pull it straight out of the fob.
- To insert a new key blade, simply align the blade with the slot in the fob and push it in until it clicks into place.
Replacing the Battery
The battery in your Lexus key fob powers the fob’s electronics. If the battery dies, you will not be able to use the fob to unlock your car or start the engine. You can replace the battery yourself by following these steps:
| Step | Instructions |
|---|---|
| 1 | Locate the battery compartment on the back of the key fob. |
| 2 | Use a small screwdriver or other sharp object to pry open the battery compartment. |
| 3 | Remove the old battery from the compartment. |
| 4 | Insert the new battery into the compartment, positive side up. |

Safety Precautions
Before delving into the process of opening a Lexus key fob, it is imperative to prioritize safety measures. Here’s a thorough guide to ensure a safe and smooth experience:
1. Verify Compatibility
Confirm that the key fob you possess is compatible with the Lexus model you drive. Incompatible key fobs may lead to malfunctions or security breaches.

Procure a small screwdriver or a pick designed for opening key fobs. These tools will assist in prying open the key fob without causing damage.
3. Choose a Safe Location
Select a well-lit and stable surface to work on, as it minimizes the risk of losing small components.
4. Disconnect Battery
If your key fob utilizes a replaceable battery, disconnect it before opening the housing. This prevents accidental activation of buttons or potential short circuits.

Apply gentle pressure when prying open the key fob. Excessive force can damage the delicate mechanisms within.
6. Avoid Sharp Objects
Refrain from using sharp objects like knives or scissors, as they can inadvertently cause cuts or damage to the key fob.

Once the key fob is open, carefully remove any loose components, such as batteries or small screws, and place them in a secure location to prevent loss.
8. Inspect Internals
Examine the internal components of the key fob for any signs of damage or corrosion. If any issues are detected, it is recommended to seek professional assistance.
9. Proper Reassembly
Reassemble the key fob meticulously, ensuring that all components are securely fitted into their designated slots. Incorrect reassembly can affect the functionality or longevity of the key fob.
