Toyota Key And Key Fob Buyers Guide
Toyotas and their keys continue to evolve along with all other automotive technology. Below we'll explain the various types of keys Toyota offers, some of their common problems and how to troubleshoot and even replace them when needed.
What Types Of Keys Does Toyota Offer?

Toyotas of the past few decades have used some combination of a wireless key fob and a mechanical key. Modern Toyota mechanical keys include an electronic immobilizer chip for security. There are also master and valet mechanical keys for situations where someone else might park your car.
Older key fobs had simple functionality to unlock the doors and cargo area. Newer Toyota smart key fobs include more advanced capabilities to start the vehicle and unlock doors automatically. Smart fobs may include an exposed or concealed mechanical key. With the introduction of push-button and remote start, most new Toyota vehicles rely solely on a key fob to enter and start the car.

Common Toyota Key Problems
After repeated use, physical metal keys can wear from friction that will dull the teeth on the key. This can make it difficult to unlock or start the car. If a replacement key is needed, the old key will be required to program the new one.
Key fobs may start to malfunction over time. Several problems can occur with key fobs, including:
- Reduced operating range
- Dead battery
- Worn buttons
- Moisture damage
- Drop damage
Always contact a qualified Toyota dealer or locksmith to program a new transponder key or key fob. If you have questions about malfunctioning fobs and replacing or reprogramming them, find the info you need here.
