A 4th Door Handle
A 4th Door HandleIn 2023, Mercedes-Benz added a 4th door handle that hides the key hole to its model line up. Thus far they are seen only on the CLE Cabriolet and 2024 GLC models.
Effectively, it continues a trend is to move away from the need to remove a piece of 
the door handle to use the mechanical key if the battery in the key fob dies.
Pulling the driver’s door handle to the open position reveal the key hole underneath the back of the handle (right). Its a simple process to then insert the key and turn to get inside. This will 
likely set off the alarm. It will shut off when the car is started.
This compliments the flush door handles first seen in 2021 Maybach models. This has now been added to AMG and EQS models in 2023, EQE, E-Class, S-Class and C-Class models in 2024. The key hole is revealed in the center of the space when the door handle is pulled open (right).

As is true with most Mercedes-Benz models, the back-up spot is marked with the image of a key with lines radiating from it (left).
evidence of Mercedes and BMW suffering from ignoring this and other trade shows.
Elsewhere, EVs remain a focus of the show, clearly an attempt to acquaint the buying public with the shift to electric driving. Volkswagen’s ID Buzz (left) made and appearance. Polestar was at the show for the first time and brought its 2, 3, and 4 models. The Polestar 4 (right) won’t be available to order for another few months with deliveries expected in 2025.
Porsche featured all four of its available electric line: the Tacan, Macan, Cayenne and Panamera (left), all open and available to crawl through. As always with Porsche, the styling is impeccable.
So lets set some parameters. Our first thought is to look for Troubleshooting chapter. So, result #1 is that not a single one of these 25 manufacturers have a chapter with this title. Only 3, Mazda (right), Toyota and Lexus, even use the word Trouble. Emergency, Roadside or Breakdown are most likely to be found, and this is a pretty short hurdle. VW raises the hurdle, with a Do It Yourself chapter that includes flat tires and dead batteries, etc. that tend to be found in the Breakdown chapters from other manufacturers.
So, back to the our troubleshooting-like chapters. Once inside, only Honda/Acura, Toyota/Lexus and Subaru got this right! Setting aside for a moment the fact that the owner’s manual is most likely inside the car and the driver locked outside, at least if the driver manages to get the car open, he or she will be able to get started.
Subaru (right), Lexus and Toyota chapters point directly to pages with solutions to issues with the electronic keys. Again, it may not be obvious to the driver that the key fob is the problem, but these manufacturers come the closest to nailing the problem. Titling the sections using something like what to do if the car does not respond to the electronic key would come closest to replicating exactly what the driver is experiencing.
We just dropped a new Mercedes Benz video
We just added a new Mercedes Benz video to our YouTube channel. It is specifically for 2019 and newer GLE and GLS SUVs as well as 2024 and newer G-Class SUVs with a dead key fob battery and in many cases a hidden key hole.
These models are the first to use a back up location in the center console storage area. Prior to this, the location was somewhere at the front of the center console.
We’ve added the video to our Mercedes Benz video page, which now features nine videos. You can find them all here at this link. The new video can be seen here.
Remember to replace the batteries in your key fobs at the first moment you see a warning on your instrument panel!
