## Before you buy

- Confirm the existing mortise cylinder dimensions, door thickness and Kwikset keyway before ordering. The listed dimensions are 2.28 x 0.69 x 1.25 inches, while the description separately calls its length 2-9/32 inch. The title says double lock cylinder, but a feature also lists a thumb-turn, so the operating configuration is inconsistent. The description says double cylinder and directs buyers seeking a single cylinder with thumb turn to another part.

## In the box

- Lock (Included)
- 2 keys (Included)

## A good fit for

- Replacing a compatible mortise cylinder in a storm or security screen door.
- Buyers whose existing lock uses a Kwikset keyway and matches the cylinder dimensions.

## Less suited to

- Doors without a mortise lock system or buyers who have not confirmed fit and keyway compatibility.

## Customer feedback

Customer feedback describes installation as easy, but reports are mixed on function and fit, and some customers raise quality-control concerns. That variability matters for a replacement cylinder because matching the stated mortise setup and dimensions is essential. Ratings lean positive overall, but the lower-star share means the aggregate alone does not settle compatibility or consistency.
- Positive themes: Customers describe installation as easy.
- Negative themes: Some customers report quality-control concerns.
- Mixed feedback: Feedback on functionality and fit is mixed, with both successful fits and reported issues.

## Frequently asked questions

### Will the Prime-Line K 5061 fit any storm door?
No universal fit is established. It is described for mortise lock systems and a Kwikset keyway, so check the existing cylinder dimensions and lock configuration.
### How many keys are included?
The listed included components are the lock and 2 keys.
### Is this a double cylinder or a thumb-turn lock?
The product description calls it a double cylinder, while a feature also mentions a thumb-turn. Because these descriptions conflict, confirm the configuration before buying.
