B2795 2018 Toyota RAV4 Code - Unmatched Key Code

B2795 indicates an "Unmatched Key Code," meaning the vehicle's immobilizer system does not recognize the key being used, preventing the engine from starting.

The primary symptoms include the engine not starting, the security light flashing on the dashboard, and the inability to unlock the vehicle using the key fob.

The code may be triggered by a damaged key, a key that hasn’t been programmed to the vehicle, a malfunctioning immobilizer system, or a fault in the wiring or immobilizer ECU.

No, a dead key fob battery typically doesn't cause this code. However, it can prevent remote unlocking, which might lead to confusion. Replacing the battery is a good first step if you’re having key issues.

You can fix the code by reprogramming the key to the immobilizer system with a specialized scan tool or by replacing a damaged key. If the issue persists, inspect the immobilizer ECU and wiring.

The code can be cleared using an OBDII scanner, but it will likely return unless the root cause of the issue, such as an unprogrammed key or faulty immobilizer, is addressed.

Not necessarily. First, verify if the key is properly programmed. If the key is undamaged and compatible, reprogramming it may resolve the issue.

The cost can vary depending on the issue. Reprogramming a key may cost $100-$300 at a dealership, while replacing an immobilizer ECU could cost significantly more, including labor.

Yes, many automotive locksmiths have the tools needed to reprogram keys and resolve immobilizer-related issues, often at a lower cost than a dealership.

No, the B2795 code typically prevents the engine from starting, so the vehicle won’t be drivable until the issue is resolved.
