When I found out that a Toyota dealership was charging over $75 to replace a sensor on my 2011 Camry (plus installation costs), I took the plunge and bought this aftermarket sensor. A nearby discount tire store had it replaced for $14. It took DT engineers two attempts to program it correctly. The first time they didn't use their programmer to reset the TPMS, they told me the warning light would go out after 20 minutes of driving. That advice was wrong. I tried using the TPMS reset button on the left side of the Camry's glove box, but that didn't work either. The second time the DT technician reset all 4 sensors and also reset the TPMS system via the OBD port to clear the system and turn off the warning light. Now everything is in order. I expect to need to replace the other 3 sensors when they become obsolete and I will do so by purchasing more of these units. Since the sensors arrive quickly and the price difference between buying one sensor and buying all 4 sensors at the same time is very small, I see no point in replacing the other 3 sensors until they fail.
