Papaiz Oval Cylinders for Multipoint Locks

Papaiz Oval Cylinder Replacements for Storm Door Locks

Oval profile cylinders serve a specific niche in door hardware, primarily used in storm doors and certain European lock systems where the traditional round Euro cylinder won't fit. MPLocks carries Papaiz oval cylinders alongside ISEO half cylinders to address the most common replacement scenarios for these distinctive lock profiles. Whether you're dealing with a worn-out thumbturn cylinder or need to upgrade to a double-keyed configuration for added security, these oval cylinders are designed to drop into existing Papaiz lock cases without modification.

Single vs. Double Keyed Cylinder Configurations

Choosing between single keyed and double keyed oval cylinders depends on your security needs and local building codes. Single keyed cylinders feature a thumbturn on the interior side, allowing quick egress without a key—ideal for primary entry points. Double keyed cylinders require a key on both sides, which can be beneficial for doors with glass panels where an intruder might break the glass to reach a thumbturn. The Papaiz C-410 offers the thumbturn convenience, while the C-400 double cylinder provides the dual-key security option for the Papaiz 323 lock case.

Oval Profile Dimensions and Compatibility

Oval cylinders have a distinctive low-profile shape measuring approximately 1-1/16 inches in height and 1/2 inch in width—significantly different from standard Euro profile cylinders. This compact design allows them to fit in narrower door stiles commonly found on storm doors and screen doors. When ordering, verify your existing cylinder length and confirm compatibility with your specific Papaiz lock case, as these cylinders are purpose-built for particular applications and are not interchangeable with standard Euro hardware.

Key Systems and Rekeying Considerations

Before purchasing, note that Papaiz cylinders use proprietary keyways and are typically not rekeyable to match your existing keys. Each cylinder comes with its own set of keys—usually two per cylinder. If you need multiple doors keyed alike, you'll want to purchase cylinders from the same manufacturer and verify keying options at the time of order. The ISEO oval half cylinder uses a European keyway and includes three keys, offering a slightly different approach for applications requiring only exterior keyed access.
