The right replacement depends on whether your ARE cover needs a key, a lock cylinder, or a complete handle. The numbered ARE replacement keys are the most relevant choice when your existing key code is 0001–0020. For a damaged cylinder, the zinc-alloy replacement may suit buyers whose measurements match. The other options are cam locks and replacement handles, so check your existing hardware and fit before ordering.
| Product | Best For | Important Check |
|---|---|---|
| ARE replacement keys | Replacing a lost key | Match the number, 0001–0020 |
| Zinc-alloy lock cylinder | Replacing a measured cylinder | Compare dimensions and mechanism |
| Teardrop L-handle | Replacing a compatible handle | Confirm rotation and mounting |
| QZATTCAEN T-handle | Replacing a left-side T-handle | Check shaft and rotation |
| Cylinnda cam locks | Thick doors or cabinets | Check lock distance and door thickness |
ARE Topper Replacement Keys
Best for: ARE topper owners who still have a lock cylinder but have lost or damaged a key. The listing provides two cut keys and covers key numbers 0001 through 0020. It is selected because it specifically names ARE topper covers and gives a key-code range, making it more targeted than a general-purpose lock.
Check the number associated with your existing key or lock before ordering. The listing does not describe a replacement cylinder or handle, so choose another option if the mechanism itself is broken. The seller’s ownership statement also means this is intended for the owner of the cover.
Zinc-Alloy Tonneau Lock Cylinder
Best for: Buyers replacing a cylinder in a tonneau cover or toolbox who can verify that the listed dimensions match their existing part. It measures 1.73 inches long and 0.85 inches in diameter, with a listed rod diameter of 0.91 inches. The listing includes two keys and specifies zinc-alloy construction.
This is a better starting point for a cylinder replacement than a complete handle when the handle still works. The product description does not establish ARE-specific fitment. Measure the old cylinder and compare its attachment and operating mechanism; matching length alone does not guarantee compatibility.
Clockwise Tonneau L-Handle
Best for: Owners whose cover uses a compatible teardrop-style L-handle and needs the whole handle replaced. This Glass Co. part is described as a clockwise locking handle with 90-degree rotation, and mounting parts are included. It is selected as a handle-level alternative when replacing only a key or cylinder would not address the problem.
Confirm the existing handle’s shape, mounting arrangement, and direction of operation before purchase. The listing does not provide dimensions or state that it fits ARE covers specifically. Avoid choosing it based only on the fact that your cover is a tonneau cover.
QZATTCAEN Left-Side T-Handle
Best for: Buyers replacing a left-side truck-cap, topper, or camper-shell T-handle with matching shaft and rotation requirements. The listing includes two keys, a dust cover, a 5/16-inch square shaft listed as 1-5/8 inches long, and a black powder-coated finish. It describes 90-degree counterclockwise rotation.
The description also says clockwise to lock and counterclockwise to unlock. Verify the direction against your existing hardware, as well as shaft size and handle placement. This is a complete T-handle option, not a standalone lock cylinder, and the listing does not confirm ARE-specific compatibility.
Cylinnda Extra-Long Cam Locks
Best for: Buyers who need a long cam lock for a thick cabinet or drawer and can adapt it to their application. The set includes two keyed-alike locks, a dust shutter, and three lock arms per lock. The description gives a 2-1/8-inch size and recommends measuring the locking distance and door thickness before purchase.
The listing presents these as cabinet locks, not as a confirmed tonneau-cover replacement. Choose this only if the mounting dimensions and cam action match the existing hardware. The product description also says multiple sets ordered together may share key control, which matters if separate keying is required.
Buying Guide: How To Choose An ARE Lock Replacement
Do you need a key, cylinder, or handle?
First identify the failed component. If the lock turns and the handle operates but the key is missing, a correctly coded replacement key may be sufficient. If the key works but the cylinder does not turn or secure the cover, measure the cylinder and inspect how it connects to the latch. If the handle is bent, loose, or damaged, compare complete handle replacements instead.
How can you check fit?
- Record the key number or code, if available, and compare it with the replacement-key range.
- Measure cylinder length, diameter, shaft or rod dimensions, and the mounting area.
- Check the handle shape, side, rotation direction, and latch connection.
- Compare the old part with product images and specifications before ordering.
Do not assume that a part fits because it is described for a tonneau cover, truck cap, or toolbox. The supplied listings do not confirm that every option fits every ARE model. When measurements or mechanism details are unclear, identify the cover and existing lock hardware before selecting a replacement.
Should you replace only the cylinder?
Choose a cylinder when the handle and latch remain serviceable and the replacement matches the existing dimensions and mechanism. A complete handle is more appropriate when the handle itself is damaged or its built-in lock is part of the failed assembly. A cam lock is a different style of hardware and should not be treated as a direct tonneau replacement without confirming fit.
Frequently Asked Questions
Are the numbered ARE keys replacement lock cylinders?
No. The ARE listing describes two cut replacement keys for numbers 0001 through 0020. It does not list a cylinder or handle.
Will the zinc-alloy cylinder fit every ARE tonneau cover?
The listing does not confirm fitment for every ARE cover. Compare its measurements and connection style with your existing cylinder before ordering.
What should I measure before buying a lock cylinder?
Measure the cylinder’s length and diameter, plus the rod or shaft and the mounting or latch connection. Compare each measurement with the product details.
When should I choose a replacement handle instead?
Choose a handle when the handle assembly is damaged or when the existing mechanism requires a complete replacement. Confirm handle shape, side, rotation, and mounting first.
Are cam locks interchangeable with tonneau lock cylinders?
Not necessarily. Cam locks use a particular mounting and rotating arm arrangement. Verify the dimensions and operation against your cover’s hardware before considering one.
