The frunk is the one part of a Tesla that still asks you to slam it. You lower the hood, it drops the last few centimetres, and nothing happens — so you push. Everyone does it, nobody likes it, and it is the single most common physical complaint about an otherwise beautifully finished car.
A soft-close lock replaces that moment with an electric suction mechanism that pulls the hood shut the final distance on its own. What almost nobody realises before ordering is that the part is generation-specific. A Model 3 is not one car for this purpose — it is three. This guide gives you the full fitment matrix, explains what the upgrade actually changes, and is straight about what it does not.
1. What Soft-Close Actually Does
A soft-close frunk lock replaces the standard latch with an electric suction unit. You lower the hood, it reaches the final few centimetres of travel, and the mechanism takes over — pulling the panel down and latching it without any push from you.
The practical result is that the frunk stops being the one part of the car you have to manhandle. For owners who use the frunk daily — which on a Model Y or Model 3 usually means it is the primary boot — that is a change you feel every single time you open it.
The mechanism takes over in the final few centimetres of travel — no push required.
2. The Fitment Matrix: Find Your Car
This is the part that matters. Order the wrong generation and the part will not fit, so confirm your exact vehicle before ordering.
| Your Tesla | Fitment | Price |
|---|---|---|
| Model 3, 2017–2020 | Dedicated part | $135 |
| Model 3, 2021–2024 | Dedicated part | $135 |
| Model 3, 2025+ refreshed | Dedicated part | $135 |
| Model Y, 2020–2024 | Dedicated part | $135 |
| Model Y, 2025+ refreshed | Dedicated part | $135 |
| Model S, 2021+ | Dedicated part | $155 |
| Model X, 2021+ | Dedicated part | $155 |
3. Why Model 3 Has Three Different Parts
Tesla revised the front-end structure across generations, and the latch is part of that structure rather than a generic component bolted on afterwards. Different hood geometry and different mounting points mean a unit designed for one generation simply will not sit correctly in another.
This is frustrating if you were hoping for one universal part, but it is also the reason a generation-specific unit works properly once fitted — it is designed for the exact geometry of your car rather than adapted to it.
4. The Two Product Lines
Both lines cover the same seven fitments at the same price points, and both replace the factory latch with an electric suction unit. Choosing between them is largely a matter of which is in stock for your car and which product page matches your model year.
Both lines cover the same seven vehicle fitments — the decision is model year first, product line second.

5. What Fitting Involves
The unit replaces the factory latch assembly, so this is a mechanical job rather than a stick-on accessory. That means removing trim in the frunk area, swapping the latch, and connecting the mechanism — and it is worth being realistic about the effort before you start.
If you are comfortable with basic trim removal and have the time, it is a well-documented job with guides available for specific models. If you are not, a professional fit is inexpensive relative to the part and removes any risk of damaging trim clips or a panel. Either way, check the product page for your specific model's fitting notes before you buy — that tells you what you are committing to.
6. What It Does Not Do
Worth being explicit, because expectations here are the usual source of disappointment:
- It does not power-open the frunk. You still release and lift it by hand — the mechanism only handles closing.
- It will not fix a misaligned hood. If the panel sits unevenly, that is an alignment issue to sort first.
- It does not replace the emergency release. The mechanical interior release still works as it always did.
- Generation still matters after purchase. Confirm your model year on the product page — this is the most common reason for a return.
7. The Companion Upgrade Almost Everyone Adds
The frunk is dark. That is the second complaint owners have about it, and it is why the soft-close lock and a frunk LED light strip get bought together so often — one fixes how the frunk closes, the other fixes the fact that you cannot see into it at night.
The LED strip is a flexible silicone unit that fits Model 3, Model Y, Highland, Model S and Model X, and at $35 it is a fraction of the lock's cost. If you are already taking the frunk apart for the lock, doing both at once saves the second round of trim removal.
Grundig Frunk LED Light Strip for Tesla
- Flexible silicone strip, waterproof and intelligent-sensing
- Fits Model 3, Model Y, Highland, Model S and Model X
- Solves the second-biggest frunk complaint: you cannot see into it
- Colour and model options available
- Fit it at the same time as the lock and only strip the trim once
8. Is It Worth It?
Honestly, it depends entirely on how often you use the frunk. On a Model Y where the frunk is the everyday load space, owners tend to describe it as one of the few modifications they notice every single day. On a car where the frunk gets opened once a month, $135 is harder to justify on feel alone.
There is also a quieter argument for it: repeatedly pushing a panel closed is not good for the hood, the latch or the paint around the contact points. Over several years, ending that habit is worth something even if you never think about it again.
9. Frequently Asked Questions
Which soft-close frunk lock fits my Tesla?
It depends on model and year. Model 3 has three separate parts — 2017–2020, 2021–2024 and 2025+ refreshed. Model Y has two — 2020–2024 and 2025+ refreshed. Model S and Model X (2021 onward) share a $155 fitment. Always confirm your exact model year on the product page before ordering.
Does it work on the Model 3 Highland?
Yes — there is a dedicated fitment for the 2025+ refreshed Model 3. It is a different part from the 2021–2024 car, so select the refreshed option specifically.
Will it open the frunk for me?
No. Soft-close handles the closing action only. You still release and lift the hood by hand, and the mechanical emergency release inside the frunk continues to work as normal.
Can I install it myself?
If you are comfortable with trim removal, it is a documented job with model-specific guides available. If not, a professional fit costs little relative to the part and avoids the risk of breaking trim clips. Check your model's fitting notes on the product page before committing.
Does it affect the warranty?
An accessory replacing a latch does not touch the drivetrain or battery warranty. As with any modification, if you are unsure or if the install involves vehicle wiring, have it fitted by a qualified professional and keep your original part.
Should I add the LED strip at the same time?
It is worth considering. The frunk is dark, the LED strip costs around $35, and fitting both in one session means removing the trim only once.
10. The Bottom Line: Identify Your Generation First
A soft-close frunk lock is one of the few Tesla accessories that changes something you physically do every time you use the car. It is also one of the easiest to order wrongly, because the model name alone is not enough to identify the part.
Find your exact model year in the fitment table above, confirm it on the product page, and consider adding the LED strip while the trim is already off. Do that and the most-complained-about panel on the car stops being a complaint at all.
Disclaimer: Fitment varies by model and model year. Always confirm compatibility for your specific vehicle on the product page before ordering, and have any installation involving vehicle wiring or trim carried out by a qualified professional.
