A:Answer The current knowledge base does not mention the ability to rekey the Eufy E35 Smart Lock to match another key, such as the Eufy E31. Smart locks typically come with manufacturer-specific key systems, and rekeying might not be a supported feature unless specified.
For this specific scenario, it's recommended to use the provided key for your existing Eufy E35 lock. If you require further clarification regarding compatibility or rekeying, please consult the Smart Lock's user manual or consider professional locksmith services that specialize in such configurations.
