Can the smart entry wear out?

Is the button under steer wheel pushed in by accident?

 

Replace the battery in the FOB.

 

The only wear item should be the fob's battery. But the system can be turned off, or suffer component failure.

 

We've owned 5 prius and when my daughter had me look at hers today (#6 prius in the family) and the smart entry didn't work- your post above fixed it-- I've never known that button existed- right next to a button to reset the Low Tire warning which I never knew existed. thanks!

 

Yes the button can get pushed by the person washing and vacuuming your car or it's kind of anything like that Glad that you were able to figure out that nothing's worn out because in our four nothing like that is ever worn out almost everything else has but this is an extreme mileage conditions too we're all above 300 K

 

Beware, that TPMS warning button isn't really a reset button, so don't use it to make a low pressure warning go away. It is meant to adjust the threshold pressure that trips the warning. Using it incorrectly may hide slow leaks.
