This only applies to cars that can be unlocked by that remote button on your key ring. Should you lock your keys in the car and the spare keys are home, and you don’t have “OnStar,” here’s your answer to the problem!
If someone has access to the spare remote at your home, call them on your cell phone (or borrow one from someone if the cell phone is locked in the car too!)

An RKE system transmits an encrypted data stream to a receiver inside the automobile via an RF (radio frequency) signal, a signal that can’t be effectively relayed via cell phone. (In any event, RKE systems and cell phones typically operate on completely different frequencies; the former in the (More than a few people have inadvertently fooled themselves into believing the cell phone method of unlocking car doors actually works because they tried it and achieved the desired It’s possible this method might work with cars that use something different than standard RKE systems, but it doesn’t work with the vast majority of models.
