Who it fits
Good fit for
You will like this lock if you want multiple ways to enter without carrying traditional keys. The inclusion of a remote control and four key fobs makes it ideal for households or small offices where several people need access. If you prefer not to manage a large set of physical keys, the PIN and RFID options provide convenience. The standard latch fits most residential doors, making installation straightforward for DIYers who can drill one hole. It suits those who value flexibility in access methods.
Who should skip it
Skip this model if you need a waterproof lock for outdoor use, as the listing states it is not waterproof and should not be exposed to direct water. You should also avoid it if your door is thicker than 2.36 inches or thinner than 1.38 inches. Note that the included metal keys are not replaceable and cannot be copied, so you must rely on the electronic methods or keep the originals safe. If you require a longer latch or different door preparation, check the available variations or additional purchases before deciding.
Verdict: The Colosus Electronic Door Lock offers solid versatility with its four access methods and included remote. It is a practical choice for standard indoor doors where key management is a concern.
Key specs for this lock
Access Methods: PIN code, RFID card, remote control, key
You can enter using a code, card, remote, or physical key. This flexibility helps when you forget a PIN or lose a card. The remote allows unlocking from a distance, useful for carrying groceries. Physical keys provide a reliable backup if batteries fail. Compare this multi-method access to single-mode smart locks that rely solely on Bluetooth or Wi-Fi.
Door thickness: 35mm to 60mm
This lock fits doors between 1.38 and 2.36 inches thick. Most standard residential doors fall within this range. You must verify your door thickness before purchasing. If your door is too thin or too thick, the lock will not install correctly. This is a critical measurement for compatibility, unlike video doorbells where mounting surface matters more.
Weight: 4.58 pounds
The unit weighs nearly 4.6 pounds, indicating a substantial build. Heavier locks often feel more secure and durable than lightweight plastic alternatives. You will need a sturdy door to support this weight. This mass suggests internal metal components rather than hollow shells. Compare this heft to lighter smart locks that may feel less robust or secure.
Package includes 4 Key Fobs, 1 Remote Control, 2 Metal Keys
You receive multiple entry options right out of the box. Four RFID fobs allow several family members easy access without sharing codes. The remote adds convenience for hands-free entry. Two metal keys serve as a last resort backup. Check if other brands include fewer fobs or lack a remote, which might require additional purchases for full functionality.
Design and build details
The listing describes the Colosus lock as a silver unit with a weight of 4.58 pounds. Its physical dimensions are 3 inches wide, 6.1 inches high, and 6.4 inches long. This mass suggests a sturdy internal mechanism that resists forced entry better than lighter plastic models. The finish is a simple silver tone, which pairs with standard door hardware.
According to the listing, the lock requires a door thickness between 35mm and 60mm. You must drill one hole to secure the lock in place. The package includes a standard 60mm latch, though an elongated 70mm version is available separately. This flexibility helps fit various door styles. The unit is not waterproof, so you should not install it where it faces direct water exposure.
Controls are managed via a touchscreen interface. The listing notes four key fobs, one remote control, and two metal keys are included. The metal keys are not replaceable and cannot be copied, so you must keep them safe. The remote allows unlocking from a distance, which adds convenience. The touchscreen provides PIN entry, while RFID cards offer another keyless option. This layout keeps the exterior clean and functional for home or office use.
Setup and everyday use
Installation requires a door thickness between 35mm and 60mm. You must drill one hole to secure the lock in place. The package includes a standard 60mm latch, though a 70mm elongated version is available for purchase. You receive four key fobs, one remote control, and two metal keys. Note that the metal keys are not replaceable and cannot be copied. This limitation means you should keep the original keys in a safe place. The unit is not waterproof, so you must avoid direct water exposure. This restricts outdoor use in rainy climates without additional shelter. The lock supports four access methods: PIN code, RFID card, remote control, and physical key. You can program these entries through the touchscreen interface. The remote allows you to unlock the door from a distance. This feature is useful when your hands are full or you are approaching the entrance. English-speaking customer support is available seven days a week in the USA. They assist with installation, programming, and troubleshooting questions. The lock fits both home and office applications. Its silver finish matches standard door hardware. The weight of 4.58 pounds suggests a solid build. Daily use involves entering your PIN, tapping an RFID card, pressing the remote button, or using a key. You can switch between these modes based on your needs. The system eliminates the need to carry traditional keys, reducing the risk of lockouts. However, the lack of waterproofing requires careful placement.
Before You Buy This Lock
You should verify that your existing door meets the 35mm to 60mm thickness requirement before purchasing. This lock is not waterproof, so you must avoid installing it where it faces direct rain or snow exposure. The package includes two metal keys, but these cannot be replaced or copied. You will need to drill one hole to secure the unit in place. Consider whether you need the optional 70mm elongated latch if your door frame differs from the standard setup. The included remote control adds convenience, but you should check battery compatibility for long-term use. This lock fits well alongside video doorbells in a smart entry system. You can pair it with a doorbell camera to see who is using the PIN or remote. This combination offers both visual verification and flexible access methods. The silver finish matches many modern home exteriors. Ensure your door style accommodates the 3-inch width and 6.1-inch height of the keypad unit. Regular maintenance of the touchscreen and remote range will keep the system reliable for daily use in homes and offices.
Check before you buy
- Check door thickness is between 35mm and 60mm.
- Ensure location is dry and not exposed to water.
- Confirm you can drill one hole for installation.

What door thicknesses fit this electronic door lock?
You need a door thickness between 35mm and 60mm for proper installation. This standard range covers most residential and office doors.

Does the Colosus lock include keys in the box?

Is the Colosus door lock waterproof for outdoor use?
No, this lock is not waterproof. You must avoid installing it where it faces direct rain or snow exposure. Moisture can damage the internal electronics and touchscreen interface. For best results, place it under a covered entryway or porch. This protects the silver finish and ensures the device functions correctly in various weather conditions.

The unit measures 3 inches wide, 6.1 inches high, and 6.4 inches long. It weighs 4.58 pounds, suggesting a sturdy internal mechanism. These dimensions allow it to fit standard door preparations. The compact design ensures it does not protrude excessively from the door frame, maintaining a clean look for your home or office entry.
Can I use the remote to unlock the door from inside?
The remote control is designed primarily for unlocking from a distance, such as approaching the door. It allows you to open the lock without touching the interface. This is useful when your hands are full. The remote pairs with the internal mechanism to provide quick, keyless entry for you and your family members using the included fobs.
What applications is this lock suitable for?
This lock is suitable for both home and office applications. Its versatile design handles the security needs of residential entries and commercial spaces.
