986 Battery Drain

[mikefocke]

If there was no power enabling a receiver of some sort, how would that receiver ever get turned on? And there has to be some power to enable the immobilizer to send the signal to turn on the circuitry to unlock the car.

Yes key fobs of different model years work differently, but the basic principle of needing a listener is still the factor.

Big power drain, no. But there is a very small drain even an hour after you have turned off the car and walked away from it. If there wasn't, you'd have to always use a mechanical key which doesn't require that listener to unlock. Not something that a healthy battery can't handle in normal situations. But a car left long enough ...

Why else do we get battery drain and condition questions after winter hibernation season ends?

….remember that these cars go into a “Deep Sleep” mode after being parked and locked for three days.

When in this mode, you must insert the key into the door to open and then stick the key into the ignition and turn it to accessory mode to disable the alarm.

My 98 Boxster doesn't do that exactly...When locked for its winter storage, I do need the key to unlock the doors...BUT I'm not required to put the key in the accessory position, or for that matter I don't need to do anything ....no NO ALARM SOUNDS. (yes, my alarm works)

Typically, I just unlock with the key, start the car and drive off.
