Buying Guide
Microchip Compatibility
Not all microchip cat doors read every type of chip. Most models from SureFlap and Cat Mate work with the common 9-, 10-, and 15-digit microchips, but always verify your cat’s chip type before purchasing. The PetSafe door exclusively reads 15-digit FDXB chips, so it may not suit pets with older chips. If you have multiple cats, check that the door can store enough IDs, most units handle up to 32 or more.

Installation Options
Microchip cat doors can be installed in doors, walls, windows, or even glass panels, but the required accessories vary. SureFlap models offer adapter kits for thicker walls or glass, while Cat Mate provides separate adapter packs for metal doors. Consider your home’s construction before choosing, a door that fits a standard wooden door may need extra work for brick or uPVC. If you are comparing pet access solutions, our smart dog door reviews offer additional installation insights.
Locking Modes and Control
Most microchip cat doors offer multiple locking modes: unlocked, locked, enter only, and exit only. The Cat Mate Elite adds a programmable timer, which is ideal for keeping your cat indoors at night or during specific hours. SureFlap DualScan even lets you set exit permissions per pet. These features give you granular control over your cat’s comings and goings. For a comparison of locking features across brands, see our best smart dog door reviews.
Battery Life and Durability
All these doors run on AA batteries, with typical life ranging from 6 to 12 months depending on usage. SureFlap models feature a low battery indicator that flashes red when replacement is needed. The Cat Mate flaps have a magnetic closure that improves weather resistance and energy efficiency. If battery longevity is a priority, look for doors with power-saving modes or optional AC adapters.

Frequently Asked Questions
Do microchip cat doors work with all microchips?
Most models support the common 9-digit (Avid Secure), 10-digit (FDXA), and 15-digit (FDXB) microchips. However, some doors, like the PetSafe model, only read 15-digit chips. Always check your cat’s microchip number with your veterinarian before buying. For more compatibility details, see our automatic cat door reviews.
Can I install a microchip cat door in a glass door?
Yes, but you will need an adapter kit specifically designed for glass or panel installation. SureFlap and Cat Mate both sell separate accessories for this purpose. Professional installation is recommended for glass doors to avoid breakage.
How long do batteries last in microchip cat doors?
Battery life typically ranges from 6 to 12 months with standard use. SureFlap models include a low battery indicator that flashes red when replacement is due. Using high-quality alkaline batteries can extend the interval between changes.
Can a microchip cat door keep my cat indoors at night?
Yes, many models offer a lock mode that prevents entry or exit. The Cat Mate Elite with timer control can automatically lock during set hours, making it easy to enforce a curfew. Other doors with 4-way locks let you manually switch to “locked” at night.
