Common Toyota Key Problems
Whether you have a mechanical key or an electronic key fob, both can get a lot of wear in everyday use. Let’s look at some common issues that can happen over time.
Mechanical Keys
If you drive an older Toyota, you may still use mechanical keys for the ignition and doors. After repeated use, physical metal keys can eventually wear down. Friction from inserting and turning the key will ultimately dull the teeth on the key. When this happens, the ignition or door lock tumblers may not align properly. The key may become difficult to turn or may not turn at all. Having a new key cut may eliminate the problem unless there is also wear in the lock cylinder.
Remember that most physical Toyota keys also have a transponder chip (often called an immobilizer) that requires programming. Besides having an embedded computer chip, the key may look like a standard physical key. The transponder chip communicates a security code to computer modules in the vehicle. Therefore, the old key will be required to program the new one. Always contact a qualified Toyota dealer or locksmith to program a new transponder key.
Smart Key Fobs

Toyota smart key fobs incorporate advanced electronics for vehicle operation and security. The smart key can function by proximity to the car to unlock the doors and cargo area without pressing any buttons. Depending on the year model, the key fob may also enable push-button start inside the vehicle. Some smart keys also offer remote-start capability.
Common problems with key fobs include:
Out Of Operating Range
The key fob may be out of signal range from the vehicle. Moving closer to the car may be all that is required to function correctly.
Dead Battery
Some Toyota models will display a low battery warning for the key fob. Replacing the battery is easy. It only requires a small screwdriver to open the fob to change out the battery.
Worn Buttons
The key fob buttons may wear out after years of use. This issue will require replacing the key fob.
Damage From Moisture
Toyota smart key fobs are water-resistant but not waterproof. The fob can withstand surface moisture, but submerging it in water will cause it to fail. Water can either short-circuit the electronics or introduce corrosion over time.
Damage From Dropping
While Toyota smart key fobs are durable, dropping on hard surfaces may eventually cause damage to the buttons or the electronics inside.

Incorrectly programming a smart key fob can put the onboard computers into lockdown mode. Once the computers are locked, they may require costly repairs, including replacing several computer modules.
