Over the weekend my 2008 Escape Hybrid manifest 2 problems the same day.
1. the remote keyless entry button stopped working (thought it was dead battery in key)
2. got a error message 'Tire Pressure Sensor Fault'

So after suffering with having to actually unlock my car with a key (heehee/see sarcastic grin) and getting irritated by the error message. I made an appointment for my car to get help at the dealership.

Meanwhile I asked the internet about my symptoms. Got the standard answers of "bad tire pressure sensor/reprogram" and change the battery in the key. But ONE and only one person (namely Enviroguy ) said what I thought was going on - that these two problems were related. (afterall it is 2 wireless devices in the car.)

Changing the key fob battery had no effect & Both keys were unresponsive.

Seeing what Enviroguy said about certain chargers or wireless devices can cause interference in the tire sensor and keyless systems. .... Then I remember that I had been using a new no-name charger for my cell phone when this problem started.

Hum.... I unplugged that charger.....(it was a cheap generic power point to USB adapter)

The Keyless system is working... !
The tire pressure error has vanished.... !

I did not go to the car appointment....

Now let's hope this was in fact the problem!
May my 2008 Ford Escape Hybrid "Be Healed!"

SO THANK you, Enviroguy, for Sharing your experience! I think you saved me a bundle!

 

yeah today my tire sensor beebd, but then was gone, this has happend about 3 times.. hmmm

 

The keyless entry and tire pressure sensors are both tied into a receiver on the vehicle. Sometimes the problem is the antenna, and other times the receiver itself is starting to go bad. My Escape had this problem and they ended up replacing the antenna, receiver, and reprogramming the key fobs before it would all work again. Personally I think it just needed a new receiver and it would have been fine once the keyfobs and tire pressure sensors were set up for it.
