PIN code door lock
A PIN code lock is an electronic entry-door security device that you unlock with a PIN code entered on a touch keypad. It fully removes the hassle of traditional keys — lost, copied or physically handed over.
A keypad lock, just like a PIN handle, lets you decide who enters your space and when — even when you're on the other side of the world — without cutting extra keys, passing them from hand to hand, or worrying that they end up in the wrong hands.
A wide range of PIN-lock applications
Electronic locks cover a broad spectrum of use cases — from apartment doors to offices and service venues. The trick is to match the features to how the space is used every day.
Apartments and short-term rentals
Short-term rentals via platforms like Airbnb or Booking put a specific challenge in front of owners: how do you safely and conveniently hand over access to guests when you're often in another city? A PIN lock solves that problem completely.
Integration with booking systems enables automatic generation of time-based codes. The guest gets the code by SMS or WhatsApp, valid exactly from check-in to check-out. You don't have to meet anyone, hand over keys or worry about copies. Once the guest leaves, the code stops working — no extra action needed.
Apartment owners report cutting guest-handling time by up to 70%. Instead of coordinating key handovers, you focus on delivering great reviews. It is an investment that pays back quickly.
Hotels and commercial venues
The wide model range at SMART-LOCK addresses hotels of every size. Managing hundreds of room doors calls for a scalable system — the TTLock app lets you control every lock from one admin account.
In hotels a PIN lock automates check-in and check-out. Guests receive their codes before arrival and reception handles more people at once or runs with a smaller crew. The entry history shows exactly who entered a room and when — especially useful for handling complaints.
Hotel staff receive their own codes or cards giving access to specific areas. Housekeeping only gets access to the floors they clean, and the technician only to plant rooms. Security and control in one. For larger venues we also recommend dedicated hotel locks.
Offices and single-family homes
In offices an electronic lock eliminates lost keys and unauthorised duplication. Each employee gets a unique code you can deactivate in seconds after they leave. The entry log lets you monitor presence — who came in first, who left last.
Single-family homes and apartments benefit from everyday convenience. Kids coming back from school don't need to carry keys. A neighbour watering the plants during your holiday gets a temporary code. And you know the door is fully secure even if you forgot your traditional key at the office.
Regardless of the venue type, professional deployment of the system matters. Let's move on to installation and support details.

Security and PIN-lock troubleshooting
An electronic lock is not just convenience — first and foremost it protects your property. SMART-LOCK uses solutions that meet the highest cybersecurity standards.
Security features and certifications
Every PIN lock we offer passes rigorous security testing. The locking mechanisms resist forced-entry attempts and the electronics are protected against tampering.
Brute-force protection (guessing sequential combinations) runs automatically — after several wrong tries the lock blocks the keypad for a set time. Communication between the app and the lock is encrypted, eliminating the risk of interception.
The manufacturer uses certified components and regularly updates firmware to close potential security gaps. This is a system that is fully safe both mechanically and digitally.
Common PIN-lock issues and how to solve them
Forgotten access code — via the TTLock app you can check existing codes or issue a new one instantly. The admin always keeps full control.
Wi-Fi or app connection issues — most locks also work offline, storing codes locally. Sync happens automatically once the connection returns. Our technical support team is there for more complex issues.
Lock malfunction — SMART-LOCK products come with a manufacturer's warranty. We deliver post-warranty service at 7 branches across Poland, guaranteeing quick repair.
Low battery — the TTLock app monitors charge level and sends early notifications. Replacing batteries is simple and doesn't require removing the whole device. Most models run for 6–12 months on a single battery set.

Frequently Asked Questions (FAQs)
What is a PIN code electronic lock
A keypad lock secures the door without a traditional key — instead, you enter your own PIN code on a touch keypad. Inside the lock is a microprocessor that verifies the entered code and sends an electrical pulse to the locking mechanism. The whole thing happens in a blink — you type the code, hear a distinctive click and the door is ready to open.
The difference between a mechanical and an electronic lock is fundamental. The former only works when you carry a physical key — and keys get lost, end up in the wrong hands or circulate uncontrollably. A PIN code electronic lock removes those problems completely — it relies on a code you remember or one stored in a mobile app. What's more, the system paired with the lock enables remote access management, temporary-code generation and full monitoring of who entered and when.
