BOLT 5/8" Receiver Lock for Chrysler, Dodge, Jeep & Ram — One-Key System, Stainless Pin

The BOLT 7018448 5/8" Receiver Lock secures Class 3–5 trailer hitches and operates with your vehicle ignition key so you don’t need an extra key for your hitch.

Designed for owners of Chrysler, Dodge, Jeep and Ram vehicles, this receiver lock uses BOLT’s patented One-Key Breakthrough system so the same key that starts your vehicle also locks your hitch. Built with a solid stainless steel 5/8" pin, an automotive-grade cylinder and weather-resistant components, it’s engineered for heavy-duty towing setups while resisting dirt, moisture and common tampering methods.

How does the BOLT receiver lock integrate with my vehicle key?

The lock is keyed to work with your vehicle’s existing ignition key, removing the need to carry a separate receiver key. BOLT’s One-Key system pairs the hitch lock to compatible Chrysler, Dodge, Jeep and Ram keys so the same key operates both ignition and hitch lock functions.

• Works with OEM ignition keys for supported vehicles (verify fitment by year/make/model).
• Eliminates extra keys on your key ring for simpler access.
• Auto-return spring secures the lock automatically when the key is removed.

Is this lock strong enough for heavy towing?

The 5/8" stainless steel pin is sized for Class 3, 4 and 5 hitches, making it appropriate for most medium- to heavy-duty towing tasks. The lock’s internal hardware and stainless cover are selected to withstand the stresses of towing and repeated use.

• Solid stainless steel 5/8" diameter pin for robust shear strength.
• Suitable for 2" to 2.5" receiver openings found in Class 3–5 setups.
• Double ball bearing locking mechanism resists pull and pry attempts.

How does it handle weather and attempted tampering?

BOLT designed the lock with a stainless steel lock shutter and a weather-resistant jacket to keep out dirt and moisture, extending service life in outdoor conditions. Anti-tamper features like a plate-tumbler sidebar and bump-resistant cylinder improve security against common lock attack methods.

• Stainless steel lock shutter blocks contaminants and moisture.
• Plate tumbler sidebar reduces vulnerability to picking and bumping.
• Weather resistant jacket protects the pin and finish from corrosion.

How easy is it to install and use daily?

Installation is straightforward: slide the 5/8" pin through the receiver and insert the lock body, then use your vehicle key to latch and secure. The auto-return spring locks the mechanism when the key is removed, so you don’t have to manually set it each time.

• Simple slide-in installation for standard 2"–2.5" receivers.
• Auto-locking action when the key is withdrawn for quick operation.
• No extra maintenance beyond occasional cleaning and lubrication as needed.

Who this is for: Drivers of Chrysler, Dodge, Jeep and Ram trucks and SUVs who tow frequently and want a convenient, heavy-duty receiver lock that uses their vehicle key. It's suited for owners of Class 3–5 hitch setups who prefer a compact, weather-resistant locking solution that reduces key clutter and adds tamper-resistant features without altering the vehicle’s ignition system.
