The Protecta EVO Express bait station is designed to resist being opened without its key, so there’s no simple trick to pop it open bare-handed. It’s a tamper-resistant station built to keep children, pets, and wildlife out of the rodenticide inside. That said, if you’ve lost your key, you have a few practical options to get the station open.
What Key the Station Uses
The Protecta EVO Express uses a two-prong plastic key manufactured by Bell Laboratories. The same key (part number PK0679) works across several stations in the EVO line, including the EVO Ambush, EVO Circuit, and Protecta Landscape models. If you have any of those other stations, the key from one will open the others.
The key inserts into a locking tab on the top of the station and releases the lid with a simple twist or push. It’s not a complex mechanism, but it is specifically shaped so that fingers or common household tools won’t easily replicate the motion.
Getting a Replacement Key
The fastest legitimate solution is ordering a replacement key. They’re inexpensive, typically a few dollars, and available from pest control supply retailers like DIY Pest Control, SenesTech, and other online vendors. Search for “Protecta EVO replacement key” or the part number PK0679. If you hired a pest control company to place the stations, calling them is the simplest route since they’ll have spare keys on hand and may come swap or service the station for you.
Opening Without the Key
If you need access right now and can’t wait for a replacement, some people have had success using a flat-head screwdriver or a pair of needle-nose pliers to depress the locking tab. The lock mechanism is a plastic latch, not a metal deadbolt. Sliding a thin, rigid tool into the key slot and pressing the internal tab in the same direction the key prongs would can release the lid. This takes some trial and error, and you risk cracking the plastic housing if you use too much force.
Another approach is to gently pry the seam where the lid meets the base using a wide flat-head screwdriver. Work slowly around the edge rather than forcing one spot. The station is built tough enough to withstand a dog chewing on it, so brute force tends to break the station before it opens it cleanly. If you do damage the housing, the station is no longer tamper-resistant and shouldn’t be reused with bait inside.
Why These Stations Are Hard to Open
The locking design isn’t arbitrary. The EPA classifies tamper-resistant bait stations by tier, and stations like the EVO Express meet Tier 1 standards, the highest level. That means they’re rated to resist entry by children under six and by dogs, withstand outdoor weather, and remain securely locked or sealed at all times. The EPA requires these stations to be anchored when in use, built from materials and colors that don’t attract children, and equipped with internal baffles that keep bait from spilling out.
These requirements exist because the bait inside is genuinely dangerous. Rodenticides can harm pets, children, and wildlife if they gain access. That’s why the station is intentionally frustrating to open without the proper key.
Safety When You Do Get It Open
Once you manage to open the station, wear nitrile or vinyl gloves before touching anything inside. Avoid breathing in dust from the interior. Deer mice and other rodents sometimes nest inside empty or active stations, and deer mice are known carriers of hantavirus, which can become airborne in dried droppings and urine. If the station looks dusty or has nesting material inside, spray the interior with a 10 percent bleach solution before disturbing it.
After handling the station or any bait, wash your hands and face thoroughly and change your clothes. If you’re removing old bait, dispose of it according to the label instructions on the rodenticide packaging. Don’t toss spent bait blocks into areas where pets or scavengers could reach them.
