Emergency Key Considerations
The emergency insert key is a vital component of your key fob. It serves as a backup in case of battery failure in the fob or issues with the keyless entry system. When you purchase a replacement key fob, it typically comes with uncut emergency insert keys.
These keys need to be cut to match your vehicle’s ignition and door lock. This can be done by:
- Lexus Dealership: They can cut the key based on your VIN.
- Locksmith: Automotive locksmiths are also equipped to cut these types of keys.
Having a cut emergency key ensures you can always access your vehicle, even if the electronic components of your key fob are not functioning.
Purchasing Your Replacement Key Fob
When purchasing a replacement 2009 Lexus ES 350 key fob, ensure you are buying from a reputable source. Genuine OEM (Original Equipment Manufacturer) key fobs are recommended for guaranteed compatibility and reliability.

By understanding your options, knowing the specifications, and choosing a reliable source for your replacement and programming, you can efficiently resolve the issue and regain full access to your vehicle’s keyless entry system.
