Model S
There are now three back up entry versions for the Model S depending on when it was built. The first two belong to vehicles that did not come with a key card. If your model did not come with a try card, try both methods below, as it is unclear where the exact build separation is.
In each case, the key fob is held to a spot on the body of the car until the key fob is recognized. Tesla uses an all electronic system, so there is no hard key and corresponding key cylinder available.
First Models
In the earliest versions of the Model S, the back of key fob is to be placed against the passenger side front fender, somewhat below and to the right of the emblem, as shown in the image. When the fob is recognized, the door handles will extend as they do normally.
The instructions in newer models note that if the car does not respond, first try repositioning the fob. Failing that, try removing the dead battery from the fob and go through the process again. This last bit really shouldn’t be necessary.
Note that it will take several seconds for the car to recognize the fob.
Newer Models
The concept is the same in the newer Model S, but the location is changed. However, it remains on the passenger side. Place the key fob near the base of the passenger side windshield wiper. The image to the right shows the exact spot that worked in the model we tested, and we tried several. Then press the driver’s door handle. The handles will extend if it is recognized, but it took a full 20 seconds in the car we tested. Try repositioning the fob if this fails. If it continues not to be recognized, try removing the battery and go back through the process.
Be patient – it took a full 20 seconds for the car to recognize the fob in the model we tested!
Models With a Key Card
If you have a key card, place it on the door frame between the front and rear doors on the driver’s side and just above the bottom of the windows, as shown in the Model 3 and Y image below. The door handles will extend inviting you inside. Thankfully, recognition is near instantaneous. The vehicle can be locked this way as well.
Model X
Tesla’s Model X uses an entirely different back up location. There again is no hard key or key cylinder. In addition, the door handles do not extend in normal operation as with the Model S. The mirrors will extend when the key fob is recognized.
Place the key fob at the base of the car on the driver’s side below the front of the rear door, as shown. If the car fails to respond, try changing the fob’s position. Finally, if the car continues not to respond, remove the battery from the fob and start over.
Once again, be patient. It may take several seconds in each position.
Model 3 and Model Y
Tesla jumped the shark with the Model 3, doing away with the key fob altogether and relying on a mobile app to get their owner’s in and started. And it works. Of course, a mobile phone’s battery can be drained in a day or less, it can fail, or the phone itself can go missing. So, the back up is a key card, the size of a credit card. No pun intended, but don’t leave home without it. The process is the same for the newer Model Y.
To get in, the key card is placed on the door frame between the front and rear doors on the driver’s side and just above the bottom of the windows, as shown. As with other models, the mirrors will extend inviting you inside. The vehicles can be locked this way as well.

U.S. Cars Sold Overseas Leave Drivers in the Dark
Drivers in the Dark, Part 1
Over the last several months we have been contacted by two drivers of U.S. cars sold and likely built overseas who could not find a back-up spot to drop the key fob in the event of the fob’s battery dying. Well, a good deal of sleuthing and a hunch resolved one of these cases.
First, we have to acknowledge the diligent work of one of the vehicles owners. He sent pics of all the spots we could think of that might be used as a back up slot and noted which style key was in use. Then after the hunch, he took the time to perform the test we suggested. The other driver essentially gave, up or possibly found an answer elsewhere and didn’t let us know.
The car in question was a Chevrolet Malibu. The owner’s manual was available and was dead wrong, which is, of course, the true source of the problem. The year, make and model in the U.S. has a back up slot in the center console.
As you can see from the photo he sent (right), the client’s car does not have this slot.
It also uses a flip key, which suggested a spot like that is used in the Cruze (right) or first generation Volt. No such plug in spot exists in the Malibu in question.
Part 2
Then, we got hold of a new, 2017 Cruze. And like a handful of other GM models, the back up slot had been moved to one of the cup holders. And, unlike European cars, the spot goes unmarked.
And while the Cruze did not use a flip key, it suggested a possible solution to our overseas client. He removed the battery from the fob and dropped it into the front cup holder, and was able to start the car (the fob will be recognized from the back up slot in GM vehicles, at least temporarily, even with the battery actually missing). He is relieved to have an actual back-up plan.
The moral of the story for drivers of U.S. designed vehicles sold overseas is this (and we include Ford as well just in case, although we have not seen this come up). If the battery in your key fob is dead, there is still a back up plan. However, your owner’s manual may not reflect it. Try each and every one of the dozen or so back up spots found on our pages. We are pretty confident one of them will get you going.
