Locksmith decision guide
Reviewed and updated September 24, 2026
August describes retrofit locks that attach on the inside while leaving existing exterior hardware and physical-key access in place. That can address one practical concern, but it does not grant landlord consent, establish compatibility with every deadbolt, or prove suitability for a fire-rated entrance. Confirm the exact lock and door with the manufacturer and the person responsible for the property.
Before installation, document who must retain access, how authorized users will enter when electronic access is unavailable, and which original parts must be kept so the entrance can be restored under the property's written approval.
Confirm exact product, provider, property, and local applicability before acting.
Choose a state to make the geographic boundary explicit.
A ZIP code does not prove compatibility, jurisdiction, price, availability, or job acceptance.
Some August retrofit locks attach on the inside while leaving exterior hardware and physical-key access in place. That feature may address one practical concern, but it does not grant permission to alter a rental property. Ask the person responsible for the property for written approval that identifies the proposed product and any restoration condition.
Use the manufacturer's current compatibility process for the exact deadbolt and door. Confirm whether the entrance has fire-rating, building-access, or association constraints with the responsible party rather than inferring approval from a marketing page. Do not assume that every single-cylinder deadbolt or every rental entrance accepts the same retrofit.
Document who retains physical-key access, how authorized users will be removed, what happens when power or the app is unavailable, and how original hardware will be stored. These are planning questions, not claims that the reviewed product provides every feature. Before installation, align the manufacturer's instructions with the landlord or property manager's written conditions.
