When I started my business as an unencrypted keypad supplier three years ago, I heard the same question over and over from small café owners, gym managers, and local shop operators: “Can my old, simple unencrypted keypad even connect to a wireless network without putting my customers or my business at risk?” At the time, I’d get half the answer from technical support teams, who’d say “it depends,” but rarely the full picture—one that balances real-world use, wireless network basics, and what unencrypted keypads actually do (and don’t) in 2024. Let’s break this down, because it’s not a yes/no question, and there are more layers to it than most people think. Unencrypted Keypad
First, let’s get one thing straight: an unencrypted keypad doesn’t mean the device can’t connect to Wi-Fi. In fact, most modern unencrypted keypads are built to pair with wireless networks—they don’t rely on old wired RS-232 ports or dedicated telephone lines anymore, which would be a nightmare for small businesses that want flexible, remote access. The confusion usually comes from mixing up two separate things: the keypad itself being unencrypted (meaning it doesn’t scramble the data it sends, like a customer’s entry code) and the wireless network it’s connecting to being encrypted. Those are two totally different pieces of the puzzle.
Let’s take a common example: a small gym that uses an unencrypted keypad to control employee entry. A few years back, gyms would use wired keypads hardwired to a control panel near the door, but today, many gyms opt for wireless keypads because they can move them if they rearrange locker rooms, and they don’t have to pay for an electrician to run cables. My company sells exactly this type of keypad—simple, budget-friendly, no fancy encryption chips, perfect for businesses that don’t need high-security access like banks or hospitals. Last year, we sold over 400 of these to small gyms across the U.S., and every single one was set up on a standard WPA2 or WPA3 wireless network. The gym managers didn’t have to upgrade their entire Wi-Fi system, or replace their old keypads, because the keypad just connects to the network like any other device.
But here’s where the real risk comes in—and this is what I wish more people understood. The keypad being unencrypted means that if someone is snooping on the wireless network, they could intercept the data the keypad sends: like a code that grants access to the gym, or even a customer’s unique entry PIN if it’s a keypad that tracks user codes. Wait, you might say—if the keypad is sending that data over the network, why not just encrypt it? For some businesses, it’s about cost. Our unencrypted keypads are 30-40% cheaper than encrypted ones, and for a small café or a community center that just needs a keypad to lock their back office or a storage room, that’s a big difference. They don’t need a keypad that can handle 10,000 unique user codes or encrypt every single entry—they just need something that works, without breaking the bank.
But does that mean it’s unsafe to connect an unencrypted keypad to a wireless network? Not necessarily—if you set up the network right. Let’s go back to that gym example. The gym’s IT guy (or even the owner, if it’s a small operation) can set up a separate, isolated wireless network just for the keypad. Most modern routers let you create a guest network or an IoT network that’s cut off from the main network that holds customer credit card info, email, or passwords. So even if someone hacks the keypad’s connection, they can’t get to the gym’s main computers that process payments or store customer data. That’s a game-changer. Last year, one of our clients—a yoga studio in Portland—set up their unencrypted keypad on an isolated IoT network, and they haven’t had any issues in two years. They told me they saved $800 by not upgrading to an encrypted keypad, and they sleep better knowing their main systems are secure.
I’ve also had customers ask me about older unencrypted keypads, the kind that were made before 2015 and don’t have Wi-Fi built in. Can you connect those to a wireless network? Sure—you just need a small wireless adapter, a $20 device that plugs into the keypad’s serial port and turns it into a Wi-Fi device. I’ve helped dozens of customers with older keypads do this, instead of making them buy a whole new keypad, which would cost hundreds of dollars. That’s the thing about being an unencrypted keypad supplier—we don’t push customers to replace perfectly good equipment. We help them work with what they have, if it makes sense.
But let’s be honest: there are scenarios where connecting an unencrypted keypad to a wireless network is a bad idea. If you’re using the keypad to access sensitive areas, like a pharmacy’s prescription storage, or a bank’s cash room, then an unencrypted keypad on a regular network is a risk. In those cases, you need a keypad that encrypts its data, or a wired connection that’s not on a wireless network at all. We sell encrypted keypads for those situations too, but most of our customers don’t need them. I once had a retail store manager come to me panicking because they thought their unencrypted keypad was going to get them hacked. I walked them through their network setup, and realized their keypad was on the same network as their point-of-sale system. We moved the keypad to an isolated network, and he was fine. No need for a new keypad, no need to pay for extra security—just a simple fix.
Another common misconception: people think that wireless networks for unencrypted keypads are less reliable than wired ones. But that’s not true, not anymore. WPA3 networks, which are the standard now for most home and small business routers, are secure enough that unless someone is actively targeting your keypad, they won’t be able to intercept its data. I’ve had customers use our unencrypted keypads on wireless networks for years, and the only issues we’ve ever had are from poor Wi-Fi signal, not from the keypad being unencrypted. A weak signal can make the keypad drop connections, but that’s a problem with the router, not the encryption of the keypad.
Let’s talk about data for a second. When an unencrypted keypad sends data, what exactly is it sending? Most unencrypted keypads for small businesses send tiny amounts of data: a signal that says “grant access” when a correct code is entered, or a notification if the code is wrong. That’s it. It’s not sending thousands of user records, it’s not sending credit card info, it’s just a short, simple signal. Even if someone did intercept that signal, all they’d get is a code, which is usually only a few digits, and most of the time, that code is only good for a short period of time or for a specific door. So even if someone snoops the network, they can’t just walk in and take over your business—they’d need way more specific information.
I’ve been in this industry long enough to see the fear around unencrypted devices. A lot of tech blogs will tell you that any unconnected wireless device is a risk, but that’s a one-size-fits-all take that doesn’t apply to small businesses. Big corporations have the budget for encrypted everything, separate networks, top-tier security teams. Most of our customers are small business owners with 10 to 50 employees, who are trying to keep their costs down and run their shops or gyms or community centers. They don’t need a $1,500 encrypted keypad when a $300 unencrypted one works perfectly, as long as they follow a few simple rules.
So what are those rules, if you’re using an unencrypted keypad and want to connect it to a wireless network? First, isolate the keypad on its own network. Don’t put it on the same network as your POS system, your email, or any devices that hold sensitive data. Second, make sure your wireless network is using WPA2 or WPA3—never use an open network with no encryption at all. If you use an open network, then anyone on the same Wi-Fi can snoop, no matter what device you’re using. Third, change the default code on your keypad. A lot of people leave the factory default code (like 1234 or 0000) on their keypads, which is a risk no matter if it’s encrypted or not. Fourth, update your keypad’s firmware when you can. Most modern keypads have small firmware updates that fix connectivity issues and sometimes add basic security tweaks, even to unencrypted models.
I once worked with a small library in rural Ohio that was using an old unencrypted keypad to lock their back storage room. They were worried because their only Wi-Fi was a weak signal from a nearby library system. We helped them get a $5 Wi-Fi extender to boost the signal, set up an isolated network just for the keypad, and change the default code. They’ve been using it for three years now, and they haven’t had a single security issue. The librarian told me it’s been a lifesaver—she no longer has to go outside to unlock the storage room when she’s working late, because the keypad is connected wirelessly from inside the library.
Is there a future where unencrypted keypads and wireless networks don’t mix? Maybe, for high-security applications, but for most small businesses, the two work perfectly fine together. The key is understanding the difference between the keypad’s encryption and the network’s security, and setting up your network to protect the data that matters. As an unencrypted keypad supplier, I don’t try to sell my customers something they don’t need. I tell them the truth: unencrypted keypads are compatible with wireless networks, as long as you follow basic network best practices. You don’t have to overspend on fancy security gear to keep your business safe.
