You definitely need to put it in neutral to move it, though, so it’s time for a little manual action. If you press the brakes, no signal is sent, and the shift lock will not disengage. When you have a dead car battery, turning the key does nothing. Normal functioning of the shift lock also requires the key to be in the “on” or “run” position, as it relies on the braking circuit to send the release signal. Mandated by law on all vehicles made after 2010 and sold in the U.S., this function prevents the transmission from shifting without also applying the brakes. It’s a small lever that jams the gear in place. To help avoid this and to prevent drivers from accidentally bumping the shift lever into neutral after parking on an incline or suddenly reversing in traffic, the brake-shift interlock was introduced. Automatics might make things easier, but they also open the door to potential damage if a driver tries to shift into reverse, park or neutral prematurely. Automatic transmissions take the guesswork out by automatically switching between drive gears based on what is required at the time. Manual transmissions require drivers to shift between drive gears according to moment-to-moment conditions.

Frustratingly, you find it’s stuck in park. Luckily, you have another car to serve as a jumper, but you’ll have to get the vehicle with the dead car battery out of the garage first.


You pack it up, step inside, turn the key and … nothing. So you left a car in the garage all winter and now would like to take it out for a nice spring drive.
