Tesla Soft-Close Doors and Frunk Lock: What They Do and What to Check First

Tesla's manuals ask you not to slam the doors or the front trunk, and a soft-close kit is meant to take the effort out of that last bit. This guide explains what the two kits do, what the seller says about them, what Tesla's manuals say about closing doors and the front trunk, and what to check before you order. The kits are third-party products, not made by Tesla, and your own manual has the final word for your car.

Why people look at soft-close

According to the seller, Tesla doors need a firm push to close properly, and a door that is not fully shut means a warning on the screen. Tesla's Model 3 manual adds a practical reason to get it right: the Walk-Away Door Lock will not engage if a door or trunk is not fully closed.

The manuals also ask for care. Tesla says that slamming or forcing the doors, the rear trunk or the front trunk can result in damage that is not covered under warranty. For the front trunk, the Model Y manual says the weight of the hood alone will not latch it. You lower it until the striker reaches the latches, press firmly on the green areas on both sides of the front edge with both hands, and then try to lift the front edge. If it moves, it is not latched. The manual says the driver is responsible for confirming it is latched before driving.

Soft-close doors

The door kit replaces the original latch in each door with an electric soft-close latch. The picture below is a simplified top view of one door edge and its pillar.

• You still close the door. You push it gently until it is nearly closed. According to the seller, the system pulls it shut once it is within about 7-9 mm.
• Anti-pinch. The seller says the system stops if it detects something in the way. Tesla's manuals still ask you to keep fingers, jewelry and acrylic nails clear of the door and handle mechanism, so treat the stop as a backup and not as permission.
• It keeps working without power. The seller says the doors can still be opened and closed if the system loses power. The listing does not say how the kit works with Tesla's manual door release or the rear child locks, so ask the seller before you order. We explain the release in our rear door release guide.
• Direct replacement. The seller says it replaces the original door latch with no cutting or drilling. It is listed as quiet, under 50 dB, with a 1-year warranty from the seller.

Soft-close frunk lock

The frunk lock is a smaller job. According to the seller, it fits into the original front trunk latch. You lower the lid until it is almost shut, and the lock pulls it closed and latches it, so you do not have to press down on a wet or dusty hood.

• About 5 mm. The seller says the lock pulls the lid shut once it is within about 5 mm of closing.
• It can close by itself. The seller lists a feature that closes the frunk automatically if it is left open for 90 seconds. Keep your hands, bags and loose items clear of the lid edge, and check the area before you close it, as Tesla's manuals ask.
• The frunk opens as before. According to the seller, it still opens the usual way, from the screen or the app.
• You still check. Tesla says the driver is responsible for making sure the front trunk is closed before driving, and describes lifting the front edge carefully to check. A lock does not change that habit.

Safety, warranty and fitting

• Doors are a safety part. The latch holds the door shut in everyday driving. The seller says that fitting the door kit means taking the door panels apart and can be challenging, and that there is a fitting video on its listing. We recommend a professional car accessories installer for the doors.
• The frunk lock is easier, but it is still a latch. The seller describes it as plug and play, with no wire cutting or drilling. If you would rather not work on the latch yourself, a car accessories installer can fit it.
• Check the warranty wording. In the edition of Tesla's New Vehicle Limited Warranty that we read (Qatar, effective July 2024), non-genuine parts and accessories, and their installation, are not covered. Damage linked to their installation or use is excluded, along with the extra parts and labor needed to fix it, and repairs or modifications by an unauthorized person or facility are excluded as well. Warranty editions differ by region, so read yours or ask Tesla before you decide.
• Confirm the fit. The versions are year-specific. The seller lists the frunk lock for the Model 3 Highland in 2025, so if yours is a 2024 car, ask the seller first.
• Check it by eye, not by force. After fitting, close the door gently and make sure it shuts fully and the screen shows no open-door warning. Do not slam it to test it.

Is it worth it?

If your doors and frunk close fine, you do not need a kit. It makes the most sense if the front trunk is something you open every day, if you often have wet hands or a dirty hood, or if people in your family tend to slam the doors. The door kit costs more effort and carries more risk to fit, because it works on the latch of every door. If you are unsure, the frunk lock is the lower-stakes place to start.
