The Short Answer
Press your remote first. If the remote opens the gate, the gate, operator, and power are all healthy and the fault is isolated to the keypad or its wiring. That is the good outcome and it narrows the repair considerably. Keypads live outdoors and take the full force of Houston weather, so the two causes we find most are corrosion on the keypad terminals from humidity and driving rain, and codes erased from the receiver by a power surge. If the remote also fails, the keypad was never the problem and you have an operator, power, or control board fault instead.
Most Likely Causes, In Order
01
Corrosion on the keypad wiring or terminals
The single most common cause in the Houston area. A keypad is a sealed-looking box mounted outdoors in a climate with brutal humidity and wind-driven rain. Moisture gets past a tired gasket or an unsealed conduit entry, works on the terminal screws and the ribbon connection, and the keypad goes intermittent before it goes dead. Green or white powder on the terminals confirms it.
02
Dead battery in a wireless keypad
Wireless keypads run on batteries, and Houston heat shortens their life well below the rated figure. The usual progression is that some presses register and others do not, then nothing. If your keypad has no wire running to the operator, this is the first thing to rule out and it is a cheap fix.
03
Access codes erased from the receiver
A nearby lightning strike or a surge on the power line can clear the receiver memory. Every stored keypad code goes with it, so a code that worked for years suddenly reports as invalid. The keypad hardware is perfectly fine — the gate simply no longer recognizes the number. This frequently happens at the same time remotes stop working, which is a useful clue.
04
Worn keypad buttons or membrane
Keypads get pressed thousands of times, in sun, heat, and rain. The membrane under the buttons cracks and the contacts beneath wear out. The giveaway is that specific digits stop registering while others still work. If the digits in your code are the ones that fail, the keypad is simply worn out.
05
No power reaching the keypad
Hardwired keypads draw low-voltage power from the operator board. A chewed wire, a corroded splice in a buried junction box, a tripped board fuse, or water in the conduit interrupts it. A keypad with no backlight and no beep when pressed is usually a power problem rather than a programming problem.
06
Someone changed or reset the code
Worth ruling out before anything else, especially on rentals, properties with staff, or after a prior service visit. Codes get changed and not communicated, and a board replacement resets everything to factory defaults. It costs nothing to confirm you are entering the current code.
What You Can Safely Check Yourself
These are all safe to do from outside the operator housing, and they will tell us before we arrive whether we are chasing a keypad, the wiring, or the receiver.
- ✓Open the gate with the remote — this proves whether the gate itself is healthy
- ✓Watch for a backlight or listen for a beep when you press a key
- ✓Press every digit 0 through 9 and note which ones respond and which do not
- ✓On a wireless keypad, replace the batteries before assuming anything else
- ✓Look at the keypad face and gasket for cracks, and at the housing for water staining
- ✓Note whether this started right after a storm, which points to erased codes
Leave the Wiring to a Technician
Reprogramming codes and inspecting keypad wiring means opening the operator enclosure, which contains line-voltage wiring, a charged backup battery, and capacitors that hold voltage after the power is cut. We do not recommend opening it. There is also a practical risk worth naming: a keypad is your access control, and the wrong approach to a dead one is propping the gate open or disabling it, which leaves your property unsecured for however long the repair takes. Replacing batteries in a wireless keypad is completely safe. Anything behind the faceplate or inside the operator is not.
When to Stop and Call Someone
Call if the remote works but the keypad does not, if the keypad shows no backlight or beep, if specific digits have stopped responding, or if the codes stopped working right after a storm. Our $89 diagnostic covers the keypad, its wiring run, the receiver, the board, and reprogramming every code and remote you have, and it is applied toward the repair. We stock common keypads, so most of these are resolved in the same visit.
Questions People Ask
Why did my gate keypad stop working but the remote still works?
Because they are two separate paths into the same gate. The remote talks to a radio receiver; the keypad is usually a wired device with its own power and terminals. If the remote opens the gate, the operator, motor, and power supply are all proven healthy and the fault is confined to the keypad, its wiring, or its stored codes. In Houston the most common answer is corrosion on the keypad terminals from humidity and wind-driven rain.
Can I reprogram my gate keypad code myself?
On most systems the programming sequence runs through the operator board, which means opening an enclosure with line-voltage wiring and a charged battery inside. We do not recommend it. If your keypad is a standalone wireless unit, code changes are sometimes done at the keypad itself, in which case the manufacturer sequence is safe to follow. When we come out we reprogram every code and remote while we are there.
My keypad lights up but the gate does not open. What does that mean?
A lit keypad means power is reaching it, so the failure is further along the chain. Either the code is no longer stored in the receiver, the signal is not getting from the keypad to the board because of a broken or corroded wire, or the board input has failed. A keypad that lights up and beeps but produces no gate movement most often means erased codes, especially after a storm.
Only some of the numbers on my keypad work. Is it worth repairing?
That is a worn membrane and the keypad is at the end of its life. The contacts under the heavily used digits wear out first, which is why the numbers in your own code tend to fail before the rest. Replacing the keypad is the correct fix rather than repairing it, and it is a straightforward job on an otherwise healthy gate.
Why do gate keypads fail so often in Houston?
Weather. A keypad is an electronic device with a membrane and exposed terminals, mounted outdoors in a climate with high humidity year-round, wind-driven rain, and intense summer heat. Moisture gets past aging gaskets and corrodes the terminals; heat degrades wireless keypad batteries faster than the rated life; and our electrical storms erase stored codes. A keypad that lasted a decade somewhere dry will not last that long here.
Can I add a smartphone option instead of replacing the keypad?
Yes, and it is a common upgrade when a keypad fails on an older system. Smartphone control and cloud access systems let you open the gate from your phone, grant access to visitors remotely, and see an entry log, without a weather-exposed keypad as the only way in. We install these alongside a keypad rather than instead of one, so you keep a way in if a phone is dead.
