Bike theft happens fast — often in under 60 seconds. A standard padlock can physically restrain a bicycle, but it cannot alert you the moment someone attempts to tamper with it. A smart alarm padlock changes that equation. By combining an NFC-based unlock mechanism with a built-in vibration detection system, it does two things at once: it keeps the bike physically secured and sounds an immediate 85 dB alarm the moment the lock is disturbed.
A smart alarm padlock is a hardened padlock equipped with an electronic vibration sensor and an NFC (Near-Field Communication) chip. When secured, the lock continuously monitors for physical disturbance. Any attempt to move, lift, or forcibly remove it triggers the alarm. To open the lock legitimately, the owner taps an authorized NFC-enabled card or device at 13.56 MHz to the lock — the alarm disarms and the shackle releases.
Jin Tay's iT805 Smart Alarm Padlock is built on this principle: combining mechanical reliability with electronic alert capability, certified under FCC (ID: 2BUZY-1JI-805NF1) and NCC standards.
iT805 Quick Reference Specifications NFC Frequency: 13.56 MHz | Alarm: 85 dB vibration alert | Water Resistance: IP54 (IEC/EN 60529) Battery: AAA | Certifications: FCC (2BUZY-1JI-805NF1) + NCC | Manufacturer: Jin Tay, Taiwan, est. 1980 |
Understanding how the iT805 works starts with recognizing that it contains two independent but coordinated systems: a mechanical locking body and an electronic alarm module. They operate together but each serves a distinct function.
Specification | iT805 Smart Alarm Padlock |
System | Function |
Mechanical body | Hardened shackle and cam lock cylinder — physically secures the object |
NFC module (13.56 MHz) | Authenticates the unlock command from an authorized card or device |
Vibration sensor | Detects physical disturbance and triggers the alarm |
Alarm module (85 dB) | Emits a loud audible alert to deter tampering and alert nearby people |
Power source | AAA battery — powers the electronic components with no charging required |
The operational logic of the iT805 follows a clear, repeatable sequence each time it is used:
1 | Secure and Lock Thread the shackle through the bike frame and a fixed anchor point such as a bike rack or post. Press the shackle down until it clicks into the locked position. The lock body is now mechanically secured. |
2 | Alarm Armed Once locked, the internal vibration sensor activates automatically. The lock is now in a monitoring state — any significant physical disturbance will trigger the alarm. |
3 | Vibration Detected — Alarm Triggers If someone attempts to lift, move, cut, or forcibly tamper with the lock or the secured bicycle, the vibration sensor detects the impact or motion. The 85 dB alarm sounds immediately. |
4 | NFC Unlock — Alarm Disarms To open the lock, the authorized user taps an NFC-enabled card or device to the lock face at 13.56 MHz. The lock authenticates the credential, the alarm disarms, and the shackle releases. |
5 | Remove and Repeat The shackle is pulled free. The lock returns to its unarmed standby state until the next locking cycle. |
Consider a commuter who locks their bicycle outside a café in a busy urban area. They loop the iT805 through the rear wheel, the frame, and a fixed bike rack — locking it in one motion. The alarm arms automatically.
Twenty minutes later, a thief approaches. They grab the bicycle by the handlebars and attempt to roll it away. The moment the bike shifts, the shackle is pulled sideways and transmits force and vibration into the lock body. The vibration sensor detects this and the 85 dB alarm activates — roughly equivalent to a car alarm or a pneumatic drill heard from a short distance.
The sound draws attention from people on the street and from inside the café. The thief, now visible and audible to others, abandons the attempt. The bicycle remains secured. The owner returns, taps their NFC card to the lock, and rides away.
Why 85 dB Is Significant 85 dB is comparable to a busy road intersection or a power lawn mower heard from one meter away. In an urban environment, this volume is difficult to ignore and immediately signals to bystanders that something is wrong — creating social pressure that deters opportunistic theft without requiring any direct confrontation. |
The bicycle use case is the iT805's primary market focus, but the same working principle applies wherever a portable, alarmed padlock is needed:
• Outdoor equipment racks at construction sites, sports facilities, or shared outdoor storage areas
• Shared bicycle or scooter programs where individual unit protection is required
• Temporary storage situations during travel, at hostels, or at transportation hubs
• OEM integration into smart locker panels or access-controlled enclosures requiring a detachable alarm lock
NFC (Near-Field Communication) is a short-range wireless standard that enables secure, contactless data exchange between devices operating at 13.56 MHz. In the iT805, NFC is used exclusively for authentication — it is not used for tracking or remote connectivity.
When the owner presents an authorized NFC card or NFC-enabled device to the lock face, the lock reads the credential wirelessly. If the credential matches, the lock releases the shackle. The 13.56 MHz frequency is an established industry standard used across payment systems, access cards, and transit passes — making it interoperable with widely available NFC technology.
NFC Authentication: The lock does not require a Bluetooth or Wi-Fi connection. The unlock event is entirely local — no internet connection or mobile app is required to operate the iT805 in its standard configuration. This keeps power consumption low and eliminates dependence on network availability. |
The iT805 is powered by a standard AAA battery. This is a deliberate design decision for practical use: AAA batteries are available at any convenience store, supermarket, or pharmacy worldwide. There is no proprietary charging cable, no docking station, and no downtime waiting for a charge cycle.
Battery life depends on usage frequency. For low-to-moderate use — typical of a commuter bicycle locked and unlocked once or twice per day — the battery supports extended operation before replacement is needed. Jin Tay recommends replacing the battery when the alarm tone weakens or the NFC response slows.
The iT805 carries an IP54 rating under the IEC/EN 60529 standard for enclosure protection:
• First digit (5): Dust protected — dust ingress is not entirely prevented, but sufficient protection from harmful deposits
• Second digit (4): Splash water protected — water splashing from any direction will not cause harmful effects
In practice, this means the iT805 functions reliably in rain and in outdoor environments where splash exposure is expected. It is not rated for submersion or high-pressure water jets. For typical urban cycling conditions — including rain, humidity, and incidental water exposure — the IP54 rating provides adequate protection for normal outdoor use.
For B2B buyers integrating the iT805 into a product program or distribution channel, certifications are a critical procurement criterion.

Q: How do I unlock an iT805 Smart Alarm Padlock? |
A: To unlock the iT805, tap an authorized NFC-enabled card or NFC-capable device to the lock face. The lock operates at 13.56 MHz and will authenticate the credential within close range. Once authenticated, the shackle releases and the alarm disarms. No PIN, no key, and no mobile app is required for the standard unlock sequence.
Q: Will rain or wet conditions trigger the alarm? |
A: No. The iT805 alarm is triggered by physical vibration and mechanical disturbance — not by water or moisture. The IP54 rating (IEC/EN 60529) means the lock is designed for outdoor exposure and handles rain and splashing water without affecting the alarm sensor or electronic components. Standard cycling conditions, including commuting in rain, are within the lock's intended operating environment.
Q: How long does the AAA battery last in the iT805? |
A: Battery life varies based on how frequently the lock is used. The AAA battery design prioritizes easy field replacement over rechargeable capacity — the battery is available in any retail outlet worldwide. Jin Tay recommends replacing the battery when you notice a reduction in alarm volume or a slower NFC response.
