We had somebody come out and move our equipment for our gate systems to the back of the office. After that, when people enter their code, it’s like the code isn’t being sent to the access system.

Gate entry systems are more delicate than most people realize. The keypad itself is just a “messenger” — it sends the signal back to the control box or access board, which then tells the gate operator to open. If wires get pulled, connections loosen, or programming gets scrambled during relocation, the keypad may power on but stop communicating with the system.
Here are the top causes when codes stop working after equipment is moved:
1. Wiring/Connection ErrorsDuring construction, when your equipment was relocated, it’s possible that low-voltage wires were misconnected or left loose. The keypad sends a signal to the gate operator; if the wiring isn’t right, that signal never reaches the motor.
DIY Check: Open the access control box. Look for disconnected or loose wires. Make sure all terminals are snug and corrosion-free.
2. Power or Grounding IssuesRelocation often means rewiring power. If your keypad or controller doesn’t have stable voltage (or lost its ground), the system won’t process codes correctly.
DIY Check: Use a multimeter to check if the keypad is receiving the proper voltage (usually 12–24V depending on the model).
3. Programming Reset NeededSometimes moving equipment wipes stored memory or resets communication between keypad and operator. That means the codes are still being entered, but the controller doesn’t recognize them.
DIY Check: Check your controller’s manual for reprogramming procedures. In many cases, re-adding user codes restores function.
4. Damaged Data Lines or ConduitsIf construction crews moved or cut into conduit, your keypad’s data line may be pinched, broken, or exposed to moisture. This is a common culprit when systems “suddenly” stop working after a relocation.
The Fix- Step 1: Technician will trace wiring from the keypad to the gate operator.
- Step 2: Confirm proper power supply and ground.
- Step 3: Reprogram or re-sync the keypad with the access controller.
- Step 4: Test multiple user codes to confirm reliability.
If damage is found, wiring repairs or controller replacement may be needed.

Pro Tip for Businesses Whenever equipment is relocated during construction, always schedule a reinspection of your access control system. Even if it looks wired correctly, subtle programming or grounding issues can leave you locked out at the worst time.Frequently Asked Questions
Most likely, wiring or programming was disrupted when the equipment was moved.
In most cases, the existing keypad can be repaired or reprogrammed. Replacement is only needed if it was physically damaged.
Yes, if remotes operate on a separate receiver, they may still work even if the keypad doesn’t. This helps narrow down the problem.
It depends on the model. Some controllers store codes in non-volatile memory, while others require re-entry after a reset.
Usually under an hour if it’s wiring or programming. More time if rewiring or a new controller is needed.
If your keypad is over 10 years old, consider upgrading to a modern system with audit trails and smartphone access.
Expect $150–$300 for diagnosis and reprogramming. If rewiring or new equipment is needed, costs increase accordingly.
