How to Unlock a Power Wheelchair

What Does Unlocking a Power Wheelchair Mean?

Unlocking can refer to disengaging the joystick controller’s electronic security lock or releasing the motors’ mechanical freewheel levers to push the chair manually. Sometimes the chair needs to be pushed by hand, perhaps because the battery is flat, it has to be moved into a car or lift, or someone needs to reposition it while it is switched off. That means releasing the motors into freewheel, or manual, mode. At other times the chair simply will not respond to the joystick, and the owner wonders whether it is locked electronically. This guide covers both situations in general terms.

Every model is different, so the owner’s manual and the supplier are always the final word. What follows explains the principles and the safety precautions that apply to most chairs, so you know what to look for and what questions to ask, without giving model-specific instructions.

Why Is an Electric Wheelchair Hard to Push When Switched Off?

Electric wheelchairs incorporate automatic electromagnetic brakes that lock the drive wheels whenever power is cut or the joystick is released. When the chair is switched off, or not being driven, these brakes hold the wheels still. That is a safety feature: it stops the chair rolling away on a slope and holds it steady during transfers. It also means that if you try to push a switched-off power chair, it will not budge, or will move only with great effort. To push it, the brakes need to be released mechanically, which is what the freewheel mechanism does.

Where Are the Freewheel Levers Located on a Power Wheelchair?

Freewheel levers are typically positioned on the rear or underside of each drive motor near the main wheels. They are usually at the back or side of the chair, low down near the drive wheels, and are often coloured or labelled so they stand out. Some chairs have one lever per motor; others have a single control that releases both. The manual will show exactly where they are and which way they move.

General Principles for Using Freewheel

• Switch the chair off at the joystick or controller first.
• Make sure the chair is on level ground, or held securely by a helper, before releasing anything.
• Move each freewheel lever to the release position as shown in the manual. On chairs with two motors, both usually need releasing.
• Move the chair slowly and steadily, holding the push handles if fitted.
• When finished, return every lever to the drive position and check the brakes hold before anyone sits in or drives the chair.

It is good practice for owners and carers to try this routine once in a calm situation, such as in the hallway at home, so it is familiar if it is ever needed urgently.

Safety Before You Push

With the motor brakes released, a power chair can roll freely, and power chairs are heavy. That creates real risks.

• Never release freewheel on a slope without someone holding the chair firmly, as it can roll away.
• Avoid pushing with someone seated unless the manual permits it and the helper can control the weight, especially on any incline.
• Remember there are no brakes in freewheel on most chairs; the person pushing must control the speed completely.
• Keep hands and feet clear of the wheels while moving the chair.

If the chair needs to go up a ramp into a vehicle, driving it under power is usually safer than pushing it in freewheel. Our guide to the attendant controlled electric power wheelchair explains how a helper can drive a chair from behind, which is often easier than pushing a heavy chair by hand.

Using Power Wheelchair Manual Mode Day to Day

Manual mode is not only for breakdowns. Carers sometimes use it to reposition an empty chair in a small bedroom, to line it up beside a bed after the user has transferred, or to move it out of the way for cleaning. In these everyday moments, the same care applies: switch off, release the levers on level ground, move the chair gently, then return everything to drive. Leaving a chair with its brakes released is a common cause of confusion later, when the user finds it will not drive or, worse, that it rolls when they lean on it to transfer. A simple habit helps, such as always checking the levers before the user sits down. If the electric wheelchair brake release is stiff or hard to reach, mention it at the next service; a technician may be able to adjust it or suggest an extension. Never try to modify the levers or brakes yourself.

How to Push an Electric Wheelchair Comfortably

Even with the brakes released, a power chair takes effort to move because of its weight. Push handles make it much easier; if your chair lacks them, ask the supplier whether they can be fitted. Push on flat, smooth ground where possible, go slowly round corners, and take care at kerbs and thresholds, where the heavy chair can jolt or tip. Two people may be needed for anything beyond a short, level distance.

Electric Wheelchair Won’t Move? Check These First

If the chair is switched on but will not drive, the cause is often something simple. General things to check, following your manual, include:

• Freewheel levers: if a lever has been left in the release position, many chairs will not drive, and some show a warning on the joystick.
• Battery charge: a flat or nearly flat battery may stop the chair. Our guide to the electric wheelchair battery explains charging and battery life.
• Charger connected: many chairs will not drive while the charger is plugged in.
• Connections: a loose battery or joystick cable can stop the chair. Check visible plugs are fully seated, without taking anything apart.
• Controller lock: some controllers have a lock function, set with a key or a button sequence, to stop others using the chair. The manual will explain how to release it.
• Error codes: flashing lights or codes on the joystick often indicate a specific fault; the manual lists what they mean.

If a charger does not seem to be working, our page on electric wheelchair chargers covers the basics of matching and checking chargers.

When to Call the Supplier

If the simple checks do not solve the problem, stop and call the supplier or service agent rather than trying repairs yourself. Contact them straight away if the chair moves unexpectedly, the brakes do not hold when the freewheel levers are in the drive position, there is a burning smell, or cables are damaged. These can indicate faults that affect safety.

If the chair came from an NHS wheelchair service, repairs are normally arranged through the service and its repair contractor; the NHS guide to wheelchairs and mobility scooters explains how services work. For privately bought chairs, an established electric wheelchair supplier with local engineers can make breakdowns much less stressful.

Being Prepared

A little preparation avoids panic. Keep the manual somewhere easy to find, or save a digital copy on your phone. Label the freewheel levers if they are not obvious, and show family members and carers how they work. Keep the supplier’s phone number with the chair. Consider breakdown cover or insurance that includes assistance, especially if the chair is used far from home.

Quick Reminders

• Switch off before touching the freewheel levers.
• Only release freewheel on level ground, or with the chair held securely.
• Return levers to drive and test the brakes before use.
• Follow the manual, and call the supplier if a fault persists.
