Why Using Simplex Locks
Simplex, by Kaba (now dormakaba), is known for rugged, all-mechanical keyless entry locks. These locks are ideal for businesses that want to eliminate keys but don’t want to rely on electronics or power sources.
Advantages:
- No batteries, wiring, or software — 100% mechanical
- Changeable user code for security updates
- Durable pushbutton interface with Grade 1 performance ratings
- Great for janitor closets, server rooms, mechanical gates, and interior offices
Disadvantages:
- Single code only — not ideal for multi-user tracking
- Requires code reset process and specialty tools to change combination
For entry-level keyless security, Simplex locks are a top choice. They’re built to last and work reliably for years with zero maintenance.
Simplex Lock Rekey
While most Simplex models don’t use traditional keys, some include optional keyed override cylinders. If your Simplex lock has this feature, we can rekey it to match your master system or issue a new key for lost access.
We carry the most common Kaba-compatible cylinders and keys, including SC1 and IC core variants, allowing us to rekey or replace these locks in one visit.
Estimated cost: $25–$45 for standard rekeying, or $45–$65 for IC core or high-security cylinder overrides. Combination reset is a separate service.
Smart Locks
Simplex locks are strictly mechanical and don’t include smart connectivity. However, for clients looking to upgrade to access control, we can install electronic alternatives or recommend dormakaba’s E-Plex series, which combines keyless entry with credential management.
Recommended Smart Upgrade: E-Plex 5000 or 7900 series — featuring PIN, RFID, and audit trail features while maintaining the rugged design and mechanical reliability of Simplex.
Smart Retrofit Options: If you want to move beyond Simplex, we offer Wi-Fi/Bluetooth-enabled smart lock replacements from trusted commercial brands that integrate with badge readers and mobile credentials.
We’ll help you evaluate whether to stay with mechanical Simplex models or transition to smarter access options while keeping security tight and functional.
Do It Yourself VS Using Professional Locksmith
Simplex locks seem straightforward but often require exact alignment, torque calibration, and specialty tools for correct installation or combination resetting. DIY errors can cause jams, failure to latch, or compromise the lock’s reliability.
DIY Pros: Possible for surface-mount models with basic templates. Code change instructions available online.
DIY Cons: Improper install may cause lock misalignment, door sag, or failed code retention. Code resets require special tools and instructions.
Professional Pros: Expert combination changes, code management, secure mounting, and warranty-backed service. We diagnose and resolve all latch and lever issues on-site.
Professional Cons: Slightly higher upfront cost, but eliminates guesswork and potential lockouts.
