If you’ve ever pulled up to a commercial parking lot, apartment complex, or office building only to find a parking lock that won’t work, you know how frustrating it can be. As a parking lock supplier who’s spent the last 12 years troubleshooting these units for property managers, maintenance teams, and business owners, I can tell you that 90% of the time, a “broken” parking lock isn’t actually defective—it just needs a targeted, step-by-step fix. Parking Lock
I’ve seen it all: a user panicking because the remote won’t open the lock, a lock stuck down in a loading zone where it’s blocking delivery trucks, and even a lock that won’t stay up for long-term parking spots. The good news is that most of these issues stem from simple, easy-to-address problems, not major manufacturing flaws. Let’s walk through how to troubleshoot a non-working parking lock, from basic checks to more in-depth diagnostics, with tips I’ve picked up working directly with end-users every day.
First, start with the most basic checks—you’d be surprised how often these are the root cause. I once got a call from a property manager who said their 20 parking locks were all “dead” on a Monday morning. When I asked if the site had a power outage over the weekend, they said yes—their building’s backup generator had failed, and the locks ran on standard 120V AC power tied to the main grid. Most people skip verifying power first, which is the single most common issue for electric parking locks, the type we supply most of.
If it’s an electric lock, confirm the power supply: check the wall outlet the lock is plugged into by swapping with a working device (like a phone charger) to see if power is flowing. For solar-powered locks (another popular model), check the solar panel for debris—dirt, leaves, or snow can block sunlight and kill charging. I’ve seen maintenance teams knock a lock’s panel askew during a landscaping job, which cuts charging by 70% in a week. For these, a quick wipe of the panel and a tweak to its angle to face direct sunlight usually fixes the problem overnight.
Next, check if the remote fob or control module is the issue, not the lock itself. A lot of users assume the lock is broken when the remote doesn’t respond, but more often than not, the fob has dead batteries. We send free replacement batteries to customers every month because this is such a common mistake. How do you test this? Most parking locks have a physical key override on the side or bottom—use that to manually lower or raise the lock, and if it works when using the key, the problem is definitely the fob or control system.
If the key works but the remote doesn’t, try re-pairing the fob to the lock. The pairing process is simple, but it’s easy to forget when a fob goes out of sync after a new lock is installed or a power reset. For our standard electric locks, pairing is as easy as inserting the key, turning it to the “on” position, pressing and holding the lock’s “open” button (usually a small red or green pin near the power port) for 3 seconds, then pressing a button on the fob until you hear a beep. If that doesn’t work, check if there are other devices nearby—like a new gate opener or security camera—that might be interfering with the fob’s signal. We’ve had customers move a new WiFi router 10 feet from the lock’s control box, which caused signal interference for weeks until they rearranged.
Now, if the lock moves with the key but feels stiff, or it won’t stay up, you’re looking at mechanical issues, not electrical ones. This is super common in areas with high humidity, salt air, or heavy use—like beachfront parking lots or busy urban garages. Dirt, grime, and rust can build up in the lock’s hinge and lifting mechanisms over time, which causes it to jam. I recommend doing a monthly visual check: lift the lock slightly, look at the base where it connects to the ground, and see if there’s debris like gravel, leaves, or rubber buildup. For a quick fix, spray a small amount of silicone lubricant (not WD-40, which attracts more dirt) into the hinge and the arm that connects the lock to the base. Wipe away excess, and test raising and lowering it a few times. This usually loosens up a jammed lock immediately.
Another mechanical issue I see a lot is a bent arm or base. If a driver tried to drive over the lock, or a maintenance truck bumped into it, the metal arm that lifts the lock can bend, which stops it from moving smoothly. I once had a customer who thought their whole lock was broken because it wouldn’t lift—turns out a delivery truck had knocked the arm at a 45-degree angle, so the motor couldn’t get enough leverage to lift it. For minor bends, you can gently bend the arm back into shape with a wrench, but if the bend is more than 1 inch, it’s safer to replace the arm (we supply replacement parts for all the locks we sell, so this is a quick fix). If the base is bent, it might need to be re-installed level—uneven ground can put strain on the lock’s motor, leading to failure over time.
If you’ve checked power, remotes, and mechanics and the lock still isn’t working, it’s time to look at the motor or control board—these are the core parts that make the lock function. Most electric parking locks have a small DC motor that runs the lifting arm, and if that motor is faulty, the lock won’t move at all. How do you test this? If you have a multimeter, set it to test voltage at the motor’s terminals when the lock is triggered. If the correct voltage is getting to the motor but it’s not running, the motor is bad. If no voltage is getting to the motor, the issue is likely the control board, which is the brain of the lock that receives signals from the remote or control panel.
I always tell customers not to try to fix a control board or motor on their own—these parts are sensitive, and incorrect wiring can make the problem worse. Instead, reach out to our team, and we can walk you through testing or send a replacement part if needed. We keep stock of all common parts for locks we’ve sold in the last 5 years, so replacements usually ship within 2 business days.
There are also a few rare issues that I’ve encountered over the years, like a lock that’s been locked out of sync with the main control system for a lot. For example, if you have a parking lot with 10 locks, all controlled by a single central panel, one lock might stop responding because it lost its address in the system. To fix this, you’ll need to re-address the lock—this is another quick step: for our central-controlled locks, you press a specific combination on the central panel to assign a new address to the lock, which reconnects it to the network.
Another rare issue is extreme weather. In temperatures below 20°F (-7°C), lubricant can thicken and make the lock jam, and in temperatures above 100°F (38°C), the motor can overheat. If you’re troubleshooting in extreme weather, give the lock 10-15 minutes to adjust to the temperature before testing it—this can often resolve the issue without any repairs.
Now, a few pro tips I’ve picked up over the years to prevent parking lock issues in the first place. First, schedule quarterly maintenance: wipe down solar panels, lubricate hinges, check for loose bolts, and test the key override. Second, train all users (drivers, maintenance teams) not to drive over the lock—we see 30% of lock damage come from drivers accidentally rolling over units that are down. Third, keep spare fobs and batteries on hand—we recommend every site keep 2 spare fobs and a pack of CR2032 batteries (the most common type for our locks) to avoid downtime.
