I'm one of the many people having problems with waking up or unlocking their M3. Lately it has gotten worse and I'm finding myself needing sometimes to reboot my phone or pull out my credit card key to unlock the door or send a cell phone request to unlock my M3. Most of the time my phone will eventually Bluetooth connect after I drive off after using the credit card key to drive the car. Apparently my android cell phone never Bluetooth connected after driving 20 minutes today. I parked and exited my car thinking the car would auto-lock after arriving at the gym. When I returned later, the car was still unlocked and parking lights still on. Since I used the credit card key and my Bluetooth never connected, I guessing the car needs to be locked by swiping the credit card key from the outside door pillar. Tesla M3 web page ... "You can lock your Model 3 without taking your phone out of your pocket by turning on the “Walk Away Lock” feature. On the touchscreen, just select “Settings” then go to “Locks” to turn it on. " - Tesla credit card key has graphics designs showing only to unlock the door ... Nothing about needing to use the credit card to lock the car when you exit. So if your having problems like me with the Bluetooth and use the credit card key, remember to make sure your car is locked after leaving.
