Pop & Lock Power Tailgate Lock for 2014–2021 Toyota Tundra — Hidden Plug-and-Play Security

The Pop & Lock PL8547TUN is a hidden, plug-and-play power tailgate lock designed to secure the tailgate of 2014–2021 Toyota Tundra trucks whenever the vehicle doors are locked.

Whether you haul tools, luggage, or gear, a vulnerable tailgate is an easy target for theft. The PL8547TUN installs inside the tailgate where it’s concealed from view and ties into your Tundra’s existing door-lock wiring so the tailgate locks automatically when you lock your truck. Constructed with reinforced nylon housing and designed for 2014–2021 Tundra models (with an optional extension harness for long-bed setups), this unit focuses on discreet, dependable security with straightforward installation.

How does this tailgate lock integrate with my Tundra’s electronics?

The PL8547TUN uses a dedicated plug-and-play T-harness to connect to your truck’s power door-lock circuit. Once connected, the tailgate locks and unlocks in sync with your factory key fob and door switches, so no extra remotes or changes to normal operation are needed.

• Plug-and-play T-harness for simple wiring connection
• Works with factory key fob lock/unlock signals
• No additional remotes or control modules required
• Optional extension harness available for long-bed compatibility

Will installation require drilling or advanced tools?

No drilling or cutting is required for most installations. The unit mounts inside the tailgate using the factory access points, and the harness plugs into existing connectors, so a typical install is quick and can be handled by a confident DIYer or any dealer/installer.

• Hidden internal mount avoids exterior modification
• Standard tools and basic panel access needed
• Clear plug-in wiring reduces installation time
• Professional installation option for extra assurance

What makes this lock tamper-resistant and durable?

The locking mechanism is concealed within the tailgate, keeping it out of sight and difficult to access for thieves. The housing is made from reinforced nylon injection-molded material that resists impact and environmental wear, so it stays functional under heavy use and in varied climates.

• Hidden internal placement resists external tampering
• Reinforced nylon construction for strength and longevity
• Weather-resistant design suited to truck use
• Reliable mechanical action tied to the vehicle’s locking system

Does this fit my 2014–2021 Toyota Tundra and long-bed models?

The PL8547TUN is engineered specifically for Toyota Tundra model years 2014 through 2021 and fits standard configurations out of the box. For long-bed versions, an optional extension harness ensures proper reach and connection so the unit functions exactly like the factory locks.

• Direct fit for 2014–2021 Toyota Tundra models
• Long-bed compatibility via optional extension harness
• No vehicle-specific reprogramming required
• Designed to integrate with factory lock behavior

Who this is for: The Pop & Lock PL8547TUN is aimed at Tundra owners who want to secure the tailgate without altering the truck’s exterior or adding extra remotes. It’s ideal for contractors, outdoor enthusiasts, and everyday drivers who regularly leave tools, gear, or cargo in the bed and prefer a discreet, factory-like locking solution that installs quickly and works seamlessly with existing door-lock controls.
