Photo-eye alignment
Both sensors are cleaned, squared up and re-secured in their brackets until the indicator lights hold steady with nothing in the opening.
Garage Door Sensor and Keypad Repair
A door that starts down and reverses, a keypad that stopped responding or a wall button that does nothing are all controls problems, not door problems. McKinney Garage Door Service traces the fault to the sensor, the wiring or the opener before replacing anything.

Signs That Need Attention
- The door starts to close, reverses, and the opener light blinks
- One sensor light is off, flickering or a different color from the other
- The outside keypad works some days and not others
- The wall button does nothing while the remote still works
Photo-eye sensors sit a few inches off the garage floor, which is exactly where a bike tire, a trash can or a stack of boxes knocks them out of line. In McKinney a keypad mounted on the door frame also takes full afternoon sun and driving rain year after year, and that is often what finally kills it.
What the Service Includes
The technician checks the controls in order, from the sensors to the wiring to the opener logic, so a working part is not swapped out on a guess. You see what failed before a replacement is quoted.
Sensor wiring and brackets
Staples, pinched wire and corroded splices behind the bracket cause faults that look like a bad sensor. Damaged runs are repaired or replaced rather than taped over.
Wall button and control wire
A dead wall control can be the button, the low-voltage wire or the terminal at the opener. Each one is tested so only the failed piece is replaced.
Keypad and codes
Outdoor keypads fail from weather and battery corrosion. The technician confirms whether it can be reset and reprogrammed or needs a compatible replacement.
Remotes and car buttons
Handheld remotes and in-car buttons are paired to the opener, and old codes are cleared when a remote has been lost or a house has changed hands.
Opener travel and force
If the sensors are fine, the reversal is often a travel limit or force setting. Those are adjusted and the door is tested closing on an obstruction.
Your Repair Options
Sensors, keypads and wall controls are usually repaired or replaced individually and the rest of the opener left alone. When the opener itself is the problem, the estimate says so plainly instead of adding parts one at a time.
Related work is covered under opener repair, and our opener troubleshooting guide lists what you can safely check yourself first. If the unit is old enough that parts are getting hard to find, the repair versus replacement guide is the better place to start. A maintenance tune-up includes a sensor and reversal test as standard.

Sensor and Keypad Questions
Why does my garage door reverse before it closes?
Most often the safety sensors are blocked, dirty or out of line, and the opener is doing exactly what it should. If the sensor lights look right, the cause is usually a travel or force setting, which McKinney Garage Door Service adjusts and then tests with an obstruction.
Can I disable the safety sensors to get the door closed?
No. The sensors are what stops the door on a child, a pet or a car bumper, and bypassing them is unsafe. If you need the door shut before the technician arrives, hold the wall button down so the door closes under your direct supervision, and keep everyone clear of the opening.
What affects the cost of sensor or keypad repair?
Whether the fix is an alignment, a wiring repair or a replacement part, and whether a compatible part is on the truck. McKinney Garage Door Service confirms the quote with you before the work starts.
Will a new keypad work with my existing opener?
Usually, as long as it matches the opener's brand and frequency, which the technician confirms from the label on the motor unit. Bring that model information to the service request and it saves time on the visit.
