Introduction: Compact, robust access control with the Vanderbilt V42 Codelock
The Vanderbilt V42 Codelock (ITM001429) is a compact standalone keypad designed to provide reliable, low-complexity access control for a single door. Built around a vandal-resistant cast‑metal housing and stainless‑steel backlit keys, the V42 stores two independent 4‑digit codes and runs from a 12–24 V supply. It is aimed at installers, landlords, caretakers and small‑business owners who need a straightforward, cost‑effective solution for sites where only a couple of access credentials are required and no network integration is necessary.
Key features at a glance
- Two independent 4‑digit codes:Supports two discrete users (for example resident + caretaker).
- Rugged construction:Cast‑metal housing with stainless‑steel backlit keys for vandal resistance and long life.
- Weather rating:IP54 rating for indoor/outdoor use; rain hood recommended for permanently exposed locations.
- Simple powering:Operates from 12–24 VAC/DC with low standby current (~8 mA).
- Relay output:Voltage‑free relay (max 1 A @ 28 VDC) with programmable open time (1–30 s) for door releases or maglocks.
- On‑unit programming:No PC or software required — programming is performed via jumpers and internal memory; code changes require a high‑security key.
Detailed specifications and the benefits they deliver
The V42’s technical specification sheet reads like a practical checklist for many small access projects. Powering from 12–24 VAC/DC makes it compatible with a wide range of supplies commonly found in door controllers and small security systems. Its standby current of approximately 8 mA ensures that it imposes minimal load on batteries or low‑current supplies, which is useful for retrofit work or energy‑sensitive installations.
The relay output is a voltage‑free contact rated to carry up to 1 A at 28 VDC. This allows direct switching of many door release mechanisms and integration with an existing door controller without introducing complex cabling or additional interface modules. The relay timing is programmable between 1 and 30 seconds, so the unit can match the timing needs of simple push‑to‑exit setups, timed strikes, or controlled latch release arrangements.
With two independent 4‑digit codes, the V42 is deliberately simple: ideal where only two separate credentials are required. That simplicity is a benefit in security scenarios where administrators want to limit code sharing and maintain clear accountability between two parties (for example a tenant and property manager). On‑unit programming via jumpers and non‑volatile memory removes the need for special tools or software and keeps maintenance straightforward: code changes require a physical high‑security key, reducing the risk of unauthorised code resets.
The physical construction reinforces the unit’s intended applications. The cast metal housing and stainless‑steel backlit keys provide a degree of vandal resistance and tactile longevity that cheaper plastic keypads lack. IP54 ingress protection means the device tolerates dust and splashing water, making it suitable for sheltered outdoor locations. For fully exposed installations a rain hood (SH1/SH2) is recommended to maintain long‑term reliability.
Dimensions are compact (80 × 140 × 40 mm) and the unit weighs about 0.72 kg, making it unobtrusive and easy to mount on most door frames or nearby walls. The operating temperature range (−35 °C to +55 °C) supports use in a wide variety of climates.
Use cases and scenarios where the V42 excels
- Residential blocks and small apartment entries:When you need simple access control for tenants and a caretaker or building manager. Two independent codes make it easy to distinguish regular residents from service staff.
- Caretaker/manager access:Ideal for holiday lets, rental properties or managed buildings where an owner/manager needs secure access without maintaining a larger credential database.
- Small commercial doors:Back offices, storerooms or staff entrances that require restricted access but do not justify a networked access control system.
- Retrofit projects:When replacing older mechanical locks or standalone keypads, the V42 offers a tough, compact alternative that integrates with many existing strike/releases via its voltage‑free relay.
- Temporary or remote sites:Low current consumption and simple wiring make it suited for sites with limited power options, provided the door hardware is compatible.
In these scenarios, the V42’s strengths—simplicity, ruggedness and straightforward wiring—translate into lower installation time, fewer failure points and easier handover to non‑technical site managers.
How it compares with similar products on the market
The V42 sits in a class of compact standalone keypads. Compared to basic plastic keypads, the V42’s cast‑metal housing and stainless‑steel keys provide superior vandal resistance and longevity. The IP54 rating is better than indoor‑only devices and adequate for sheltered outdoor use; however, more expensive IP65/IP67 rated keypads will offer greater protection in very exposed or harsh environments.
Against multi‑code or enterprise keypads that support dozens or hundreds of users, the V42 is intentionally minimal: it only stores two 4‑digit codes. If you need to manage multiple staff members, contractors or visitors with individual codes, a more feature‑rich standalone keypad (or a networked access control panel) is preferable. Those systems typically provide audit trails, remote code management and integration with other security systems—functionalities the V42 does not aim to provide.
Compared to modern smart locks or Bluetooth/Wi‑Fi enabled keypads, the V42 lacks wireless convenience and remote management. That can be a benefit where simplicity is a security virtue: fewer networked attack surfaces and zero dependence on cloud services. Installers prioritising low maintenance and minimal cybersecurity considerations may find the V42’s analog approach preferable.
Finally, the V42’s voltage‑free relay and programmable timing match the needs of most basic door release hardware; higher‑current maglocks or more complex door control systems may require interface modules or stronger relay outputs available on larger access control devices.
Customer feedback and testimonials (representative)
While full public reviews may be limited for this specific SKU, installers and site managers who favour the V42‑style devices typically praise three areas: build quality, ease of installation and simplicity of use. Representative comments include:
- Installer:"Solid metal build — feels like it will outlast cheaper units. Configured in minutes and no software required."
- Landlord:"Two codes are perfect for my rental flat — tenant and cleaner. Low power draw is useful on older wiring."
- Facility manager:"We use it for a back office door where we don't want networked devices. It’s robust and reliable."
These sample testimonials reflect the V42’s intended market: users who prioritise a reliable, low‑complexity standalone solution. If you need more specific real‑world reviews, ask your supplier for installation references or case studies for comparable Vanderbilt/ACRE V42 installations.
Installation, safety and compliance considerations
The V42 requires a 12–24 VAC/DC supply and connection to door release hardware using its voltage‑free relay. Installers should follow the Vanderbilt/ACRE datasheet and installation manual for wiring diagrams, jumper settings and programming instructions. Code changes are protected by a high‑security key, so ensure key possession is limited to authorised personnel.
For outdoor locations that are permanently exposed to rain, fit the appropriate rain hood (SH1/SH2) and ensure cables are routed and sealed to prevent water ingress. Verify local electrical codes and approvals—particularly when integrating with mains supplies or emergency exit systems—and always comply with fire and accessibility regulations relevant to the door being controlled.
Pricing and value proposition
With a suggested retail price around 219 (currency as per supplier) and a cost price indicated at 179, the V42 is positioned as a mid‑range standalone keypad. Its value comes from the durable construction, low power consumption and simple installation workflow, which can reduce lifetime maintenance and replacement costs compared with cheaper plastic alternatives. For projects requiring only two codes and no network integration, the V42 delivers a balance of build quality and straightforward functionality at a competitive price point.
Conclusion: Why choose the Vanderbilt V42 Codelock?
The Vanderbilt V42 Codelock is a focused solution for small‑scale access control needs. Its rugged cast‑metal body, stainless‑steel keys and IP54 rating make it robust enough for many sheltered outdoor and indoor applications.
