Understanding Key Card Door Locks
Before diving into specific models, I learned that key card door locks operate using a card that contains a magnetic strip or RFID chip.

There are two main types of key cards: magnetic stripe and RFID cards. I realized RFID cards are generally more secure because they can’t be easily duplicated. I opted for a model that used RFID technology.
3. User Capacity
If you live with family or plan to rent out space, consider how many users can be programmed into the lock. I appreciated models that allowed multiple cards, as it made access seamless for everyone.

I discovered that battery-operated locks are common, so I looked for models with long battery life and low-battery alerts. Some locks even have a backup key option or USB port for emergencies, which I found reassuring.
5. Installation Process
I wanted a lock that was easy to install. Some models require professional installation, while others are user-friendly enough for DIY enthusiasts. I opted for a lock that didn’t require extensive tools or expertise.

I noticed that key card door locks vary widely in price. Basic models can start around $100, while high-end options with advanced features can exceed $500. I set a budget based on the features I deemed essential, ensuring I didn’t overspend but still got a reliable lock.
