Open and Start Audi A3 and Q3
Open and Start Audi A3 and Q3We recently updated our video demonstrating how to open and start Audi A3 and Q3 with a dead key fob battery. As of 2020, the models hide the key hole behind a cap at the back of the driver’s door handle, but we get you past this obstacle.
Earlier A3 and Q3 models have a visible key hole. You can find our video covering these older cars here.
Of course, starting the car assumes that the start battery is good. And if not, we will can get you inside and ready for a jump start.
We added the video to our Audi video page, which now holds now 21 videos, covering Volkswagen models as well. You can see the page here. You can also see the video on YouTube here.

When to call service
Now I immediately knew that there was no model in the related line up that would ever see paint damage when getting to the key hole. He walked me over to one, a 5-Series, and I had the cap hiding the lock cylinder off in a single move. See the instructions 
Buick opening instructions
Removing the cap requires pulling the handle out and using the mechanical key to press on a difficult to see spot. See 
To start a Mercedes-Benz that uses the tapered SmartKey style, the engine Start / Stop ignition button must be removed. It appears to ‘float’ above the dashboard and is easily pulled away from the ignition lock. Insert the tapered end of the KEYLESS-GO key in the ignition lock and turn it to start and operate old school style.
Beginning in 2017, the ignition lock in AMG roadsters and coupes is found at the back of the center console storage area, as shown in the image. Insert the tapered key fob into the ignition lock and turn it to start and operate old school style.
Models using the new, rounded SmartKey fob styles , shown to the left, require that the fob be placed in a back up location or slot. These models, as of the 2019 model year, are the AMG, C-Class, E-Class and S-Class.
The new SmartKey fob style had spread through nearly the entire product line by the 2019 model year. However, the mark (the image of a metal key with lines radiating from it) is found in or near cup holders, which are at the front of the center console. See the two images at left. The 2021 S-Class Maybach uses the rear cup holder as well (second image) as well as a newer key fob. It is similar to the one shown above.
Also in 2019, Mercedes-Benz introduced the first of its electric and electrified models, the GLC 350e. And while the mark is also found in the cup holder, it too uses the image of the SmartKey (see the image to the right), like the updated C-Class models noted above. This will likely take over all model lines with time.
Finally come a small number of exceptions. Since 2019, the GLE and GLS SUVS use a slot, with the mark of a key with lines radiating from it, is found inside the center console storage area in the front. G-Class SUVs joined them in 2024. See the image to the left. Drop the key fob into the slot and start the vehicle as normal.
Note: If you have made an attempt to start the vehicle without success, there may be residual pressure in the brake system and a new warning light may appear (left) or text message to Step on the Brake. Press the brake pedal very, very hard when trying to start the vehicle again to be sure that the release switch behind the pedal is engaged. Or wait a few minutes and try again.
Kia back up entry update includes a new entry method
We have a new Kia back up entry update and, very much like we stated for Hyundai, the new processes make us wish they’d make up their minds. Back up entry processes are necessary for those moments when the key fob’s battery dies, which happens all too often. There is a brand new way to expose the key hole on the new EV9 and, again like parent Hyundai, the company has a new mechanical key that is separate from the key fob. Kia also has new digital — smart phone — access options.
We’ll say again, and keep saying it, that we really dislike the idea of mechanical keys not being integrated into the fob. The mechanical keys can easily be lost or simply left behind, and digital options on the smart phone have proven to be less than 100% effective and requires the start battery to be charged. A mechanical key is always 100% effective!
You can see the back entry page here. BTW, the page has become so unwieldy we intend to separate the three manufacturers. Soon.
