Autofy Helmet Lock Review 2026: Keep Your Helmet Safe on Any Bike for Under Rs 300

You park outside the office, the metro station or the sabzi mandi, walk away for twenty minutes, and come back to find your helmet gone. It happens every day in Indian parking lots, and replacing a good helmet costs far more than a lock. Autofy sells three 4 digit combination locks, all under Rs 300, that let you tie your helmet to the bike itself. We read each official product page closely to explain which one suits which rider, how to set the code, and what a lock like this can and cannot do.

How do you lock a helmet to a bike or scooter?

The idea is simple: pass a steel cable through a solid part of the helmet and around a fixed part of the vehicle, then close it with a combination you choose. Most bikes and scooters have a small helmet hook under the seat, but it only holds the helmet by its D ring, and anyone can simply unbuckle or cut the strap. A cable lock ties the helmet shell itself to the frame, which is far harder to walk away with.

• Loop through the helmet, not just the strap. Pass the cable through the visor opening or the chin bar opening of a full face helmet, so the shell is held, not only the chin strap. A strap alone can be cut in seconds.
• Anchor to something that does not unbolt. Good spots are the grab rail, the frame near the footrest, or the pillion footrest bracket. Avoid mirrors and plastic panels.
• Keep it off the ground. A lock lying on the road is easier to attack and the helmet gets dirty. Pull it snug and high.
• Scramble the digits after locking. Roll all four wheels away from your code every time.
• Carry a second helmet for the pillion. The law needs both of you in helmets, and a longer cable can hold two helmets together.

Which Autofy lock should you buy: heavy duty, 12mm or cable?

All three are 4 digit combination locks, so there is no key to lose. The differences are in the build and the price. Here is what each product page actually states.

Autofy Heavy Duty 4 Digit Helmet Lock: the one we would pick

The heavy duty lock has the most detailed spec sheet of the three. Autofy lists a steel wire spine 1.2 cm in diameter inside a high density rubber coating, number rings made of premium plastic with a crisp rotating mechanism, and a toothed steel latch for solid interlocking. The rubber coat also means it will not scratch your paint or your helmet shell. For Rs 10 more than the others, you get the clearest build information, which is why it is our default pick for daily riders.

Autofy 4 Digit 12mm Helmet Lock: the budget all rounder

The 12mm resettable helmet lock costs Rs 279 and is sold as a multipurpose lock for helmets, cycles and bags. Its page lists a steel cable with a scratch resistant PVC coating, and colours are dispatched at random from stock. It suits riders who want a simple, light lock that lives under the seat.

Autofy Wire Cable Lock: for cycles and bags too

The 4 digit wire cable lock is also Rs 279 and is pitched first as a cycle lock, with helmet use as a bonus. If your household has a bicycle as well as a scooter, this one moves easily between them. Stock of this model is lower than the two helmet locks, so the heavy duty or 12mm lock is the easier buy right now.

How do you set or reset the 4 digit code?

Autofy explains the reset steps on the heavy duty lock page, and the factory code is 0000. Do this at home before your first ride:

• Open the lock with the current code (0000 when new).
• With the lock open, turn the code reset wheel marked "set" 90 degrees clockwise.
• Rotate the numbered discs one by one to your new combination.
• Turn the reset wheel back anti clockwise to its starting position.
• Close and test the new code a few times before you rely on it.

Autofy says the code can be set and reset any number of times. The 12mm lock page does not give its own steps; general guidance for most resettable combination locks is similar (open the lock, use the reset lever or wheel, set the digits, return it), but follow the leaflet in the box if it differs. Pick a code you will remember, and avoid 1234, your birth year or your number plate digits.

Is a helmet lock theft proof?

No, and it is worth being clear about this. A cable or helmet lock is a deterrent, not a guarantee. A determined thief with bolt cutters can cut any cable of this size, and four digit wheels can in theory be worked through with enough time. What the lock does very well is stop the opportunist: the person who sees a helmet hanging loose on a mirror and walks off with it in two seconds. Most helmet thefts in parking lots are exactly that kind.

So park where people can see your bike, under CCTV where possible, and never leave an expensive helmet locked outside overnight. If you ride a premium helmet worth several thousand rupees, carrying it with you is still the safest option.

Pros and cons of Autofy helmet locks

What else helps keep your two wheeler safe and ready?

A lock is one part of a good parking routine. A waterproof bike cover keeps rain and dust off the seat and hides what is parked underneath, and it also keeps your locked helmet dry. For your hands on the daily commute, FANTOM riding gloves add grip and protection for under Rs 400.

Riding home after dark from that same parking lot? A brighter beam from the NightHawk H4 LED headlight makes potholes and parked cars far easier to spot. And if you ride long distances with your phone on the handlebar, the Motoplay bike navigation screen gives you maps on a dedicated waterproof display.

Key takeaways

• Loop the lock through the helmet shell (visor or chin bar opening) and a fixed part of the frame, never through the chin strap only.
• The Heavy Duty lock (Rs 289) has the clearest spec: 1.2 cm steel wire spine, rubber coat, toothed steel latch.
• The 12mm lock and wire cable lock (both Rs 279) are good budget options for helmets, cycles and bags.
• Factory code on the heavy duty lock is 0000; reset it before first use.
• Any cable lock is a deterrent against casual theft, not protection against cutters.
