How to lubricate the garage door and replace remote batteries
To lubricate a garage door about every six months, close the door, disconnect the opener and wipe the tracks clean. Spray silicone or white lithium lubricant on the roller bearings, hinges, bearing plates, springs and lock. Leave the tracks dry. Then change the remote and keypad batteries and test the door's safety reverse.
How often to lubricate a garage door
| Job | How often |
|---|---|
| Lubricate moving parts | About every 6 months, more often in harsh climates |
| Wipe the tracks clean | Each time you lubricate |
| Check bolts, hinges and rollers | Each time you lubricate |
| Remote and keypad batteries | No set interval. Replace when range shrinks or the keypad stops responding |
A light touch matters more than the schedule. Extra lubricant collects dust and grime, which is the problem you were trying to prevent.
Garage door lubricant and other supplies
- Silicone spray or white lithium grease spray with a thin straw. The straw reaches the small ball bearings inside each roller.
- A vacuum and a damp rag for the tracks
- Gloves and safety glasses, since sprays drip from overhead
- A sturdy step ladder for the springs and top rail
- A wrench for loose nuts and bolts
- New batteries. Open the remote and match the size printed on the old one.
Skip standard WD-40 for this job. It can attract dirt. Keep children and pets out of the garage while you work, and keep flammable sprays away from the opener's electrical parts.
How to lubricate a garage door and change remote batteries
- Close the door and cut the power
Keep the door fully down and disconnect the opener before you start.
- Clean the tracks
Vacuum out the debris and wipe with a damp rag. Leave them bare, because lubricant on the tracks can make the rollers slip.
- Spray the rollers and hinges
Aim the straw at the roller bearings, not the wheels, and at each hinge pivot. CRC warns that spraying the wheels risks slippage.
- Coat the bearing plates and springs
Give the round bearing plates and the springs a light spray from the ladder. Don't touch or adjust the springs.
- Finish the top rail and lock
If your opener has a chain or screw drive, lubricate it and the top rail where it travels. Then spray the door lock.
- Spread the lubricant
Open and close the door by hand a few times and wipe off any drips. Tighten loose nuts and bolts you noticed along the way.
- Change batteries and retest
Swap the batteries in each remote and the outside keypad. Reconnect the opener, try every remote, and run the auto-reverse test your owner's manual describes.
Garage door maintenance warning signs
- Noise or rough movement that doesn't improve after lubricating. Stop and call a technician.
- Bent or damaged springs. These get replaced, not repaired.
- Frayed lift cables or loose brackets.
- A door that feels unusually heavy when you lift it by hand, or won't stay where you leave it.
- A door that doesn't reverse in the safety test. Stop using the opener until it's fixed, because that test protects people and pets.
How to lubricate a garage door safely, and when to call a pro
Cleaning, spraying and batteries are DIY. A light coat of spray on a spring is fine, as long as you don't touch, adjust or loosen anything on it. Springs and their cables are under high tension, and Bob Vila's guide warns that replacing them can cause serious injuries. Hire a qualified garage door technician for any spring or cable work.
Garage door lubricant questions
Can I use WD-40 on my garage door?
Avoid standard WD-40 for this job, because it can attract dirt. Use a silicone spray or a white lithium grease spray made for the purpose.
Should you lubricate garage door tracks?
No. Clean them with a vacuum and a damp rag and leave them dry. Lubricant on the tracks can make the rollers slip.
How often should a garage door be lubricated?
About every six months. Do it more often if you live in a harsh climate, and keep the coat light so it doesn't collect grime.
