For a long time, key fobs have controlled the automobile sales key industry. Even in 2019, keyless ignition was found in 91 percent of model-year autos.
However, BMW and its premium automobiles were ahead of the curve. For the last two decades, BMW automobiles have sold key remotes. With the release of its digital key in 2021, there are no indicators that its status will shift. Aside from the digital key, the regular fob model menu looks like this: Ignition using a Turn-in-Key
This version comes with a metal blade that you push into the ignition and turn to the start position. It still features a lock and unlock function along with a hold-release trunk button. Plus, the panic alarm is always handy, so you don’t ever have to search for the car in the parking lot.
Keyless (Non-Comfort Access) Entry
To start your BMW, you don’t need a typical metal blade using a Non-Comfort Access key fob. A panic alarm, an unlock and lock button, and a trunk release feature are all included on the remote. Push-to-Start ignitions are available on BMW models equipped with these devices, but you’ll need to slip your key fob into a slot near the steering wheel.

To unlock, lock, or start and stop your car, you don’t need to remove this BMW Key Fob. The ignition is the only button you need to press.
BMW Keyless Entry vs. Comfort Access
Although BMW Comfort Access and keyless entry are similar, there are a few major differences. The following items are included in both key fobs:

- Ignition by pushing a button
Comfort Access, on the other hand, features a proximity function. This function allows you to open your automobile door simply by touching the handle while you’re within 5 feet of it. You may also lock your doors by touching the top of the handle.
It’s also possible to open your trunk. With Comfort Access keys and Automatic Tailgate, you can open the gate with a simple tap of your foot. A sensor in certain models detects the tap and opens and shuts your trunk automatically. Comfort Access also entails keeping your BMW key fob in your pocket when starting and stopping your car.
