Turn on SOS: Press and hold [opened padlock🔓]button, when LED indicator goes off and display for a long pause then be bright, press [⚡] button, the alarm will sound a beep, then 5 beeps ,the function is on. If 2 long beeps, setting is failure. (keep the alarm still when setting) Turn off SOS: press and hold [opened padlock🔓] button, when LED indicator goes off and display for a long pause then be bright,press [⚡] button, then 2 long beeps will turn off the function. Next, press [opened padlock🔓] button to exit the setting. Power off the alarm will turn off SOS function too. **Q: I have a sh honda 125i will this interfere with my key fob to start my bike** A: How to pair? You have to open alarm box(not so easy because it's water proof) then remove all 3 batt. and after some time put them again. Before close alarm box check up pairing. **Q: Would this work for a powerchair? It doesn’t have any keys** A: IT will work on anything that moves even doors, windows etc, you can pop it in your pocket, arm it and if you move the alarm will go off :) you can fall asleep drunk & if anyone tries to rob your pockets it`ll wake you up :) **Q: Could I use this placed in a pocket in a rucksack in a tent at night?** A: As long as you don’t need to disturb the ruck sack ? I use it on an outside shed and as soon as some tries to open the door it sets a 1 second warning off then it rings if I persists with trying to get in, it’s a great bit of kit that as a lot more uses than a bike , the arm and disarm beep is a touch loud But if it’s in your bag it would be fine ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth the money *by on Reviewed in the United Kingdom 23 May 2026* Amazing bit of kit, instantly puts a very loud alarm on anything you attach it to, 100% worth the money. ### ⭐⭐⭐⭐⭐ Fantastic, best buy of the year :) *by on Reviewed in the United Kingdom 7 September 2019* Does exactly what it says. Not visible under our bike cover and I think just removing the cover would set it off. The alarm is very loud! I have set it off twice accidentally, once with the garden broom when I gently knocked the bikes and once when I caught it with water from the garden hose. It stopoed quite quickly, but from testing it we know if disturbed again it goes off for longer and is so loud we have to keep the control out where we can see it, definitely wouldn't want to be rummaging in a drawer while it is going off! The bikes are chained together, but from past experience that is no deterrent. So glad we didn't pay out for an expensive padlock and chain. No chance of anyone taking our bikes now, not without us hearing. Great to have the bikes out of the house again. ### ⭐⭐⭐⭐ Loud! *by on Reviewed in the United Kingdom 2 August 2020* Really great product. Gives me great peace of mind when the bike is locked up at night, good and loud. The only downside is that it is rather loud when you deactivate the alarm also- It would be nice to have the option to quietly deactivate it as sometimes I set of riding early in the morning and I hate to think I’ve woken my neighbours up. ## Frequently Bought Together - Mengshen Bicycle Alarm, Wireless Anti-Theft Burglar Security Alarm for Bike Motorcycle Car Vehicles Door Window, 113db Super Loud and Waterproof (Remote Control Included) - CARTMAN Vehicle Steering Wheel Lock Car Anti Theft Security Lock with Adjustable Length Fit for Cars Trucks Vans and SUVs - CARTMAN Steering Wheel Brake Lock Vehicle Anti Theft Security Brake Pedal Lock with Adjustable Length Fit for Distance from Steering Wheel to Pedal Within 21in to 30in Red --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/51787719-bicycle-motorcycle-alarm](https://www.desertcart.no/products/51787719-bicycle-motorcycle-alarm) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-10-17*
