Bmw 335I Gt Xdrive Trunk Locks

Bmw 335I Gt Xdrive Trunk locks

Starting at $46.95, AutoBuffy stocks 2 trunk lock options from URO to fit the Bmw 335I Gt Xdrive. The trunk lock secures the rear latch and allows the lid to open via key, interior release, or remote. When it fails, you may be locked out of your trunk entirely or unable to keep it shut — both are real safety and security concerns.

Signs your Bmw 335I Gt Xdrive needs a new trunk lock

  • Trunk lid will not open with the key, even when the key turns smoothly
  • Trunk pops open on its own or fails to latch securely after closing
  • Key turns but nothing happens — the actuator rod or lock cylinder has disconnected internally
  • Remote key fob triggers the latch but the lid stays shut, pointing to a failed lock actuator
  • Visible corrosion, rust, or a broken housing around the lock cylinder
  • Trunk can only be opened from the interior release but not from the outside key or fob

Which trunk lock should you buy for your Bmw 335I Gt Xdrive?

The main decision is whether you need just the lock cylinder, the full latch-and-actuator assembly, or a complete integrated unit that combines both. Many late-model vehicles use a powered actuator built into the latch, so replacing only the cylinder will not fix an electrical failure. Match the replacement to the root cause of your problem.

Lock Cylinder Only
Best for
Key won't turn or cylinder is worn/broken; actuator and latch are still functional
What you get
The keyed barrel that replaces the physical tumbler mechanism without disturbing the latch
Trunk Latch Assembly
Best for
Trunk won't latch shut or the internal ratchet mechanism is broken; key/fob function is fine
What you get
The full mechanical latch that catches the striker pin and holds the lid closed
Trunk Lock Actuator
Best for
Fob or interior release stopped working; key cylinder is still functional
What you get
The electric motor and linkage that pulls the latch open on command from the remote or interior switch
Complete Trunk Lock & Actuator Assembly
Best for
Multiple failures at once, high mileage, or a one-stop repair to avoid revisiting the job
What you get
A fully integrated unit combining the latch, actuator, and sometimes the cylinder — closest to OE fit and function

Replacing a trunk lock on a Bmw 335I Gt Xdrive

Moderate⏱ 1–2 hoursTrim panel removal tool (to pull interior trunk liner or panel)Screwdrivers (flathead and Phillips)Socket and ratchet setNeedle-nose pliers (for actuator rods and retaining clips)Multimeter (if diagnosing an electrical actuator issue)

Begin by removing the interior trunk liner or access panel to expose the latch and lock assembly, then disconnect any actuator wiring harness connectors and carefully unclip the rod linkages before unbolting the old unit. Transfer any rods or clips to the new part if they are not included, then bolt the replacement in place, reconnect wiring, and test key, fob, and interior release functions before reinstalling the trim panel. The job is straightforward for anyone comfortable with basic trim removal, but take care not to bend actuator rods during installation as this is a common cause of failure after DIY replacement.

Frequently asked questions

How much does it cost to replace trunk locks on a Bmw 335I Gt Xdrive?
Parts start at $46.95 for the Bmw 335I Gt Xdrive at AutoBuffy. A lock cylinder alone sits at the lower end of the range, while a complete latch-and-actuator assembly costs more. Add one to two hours of shop labor if you are not doing it yourself. DIY installation keeps the total cost close to the part price alone.
Can I replace just the trunk lock cylinder without replacing the whole latch on my Bmw 335I Gt Xdrive?
Yes, if the cylinder is the only failed component. If the key turns freely but nothing moves, the fault is usually a disconnected rod or broken actuator, not the cylinder itself. Diagnose first — replacing only what is broken saves money, but swapping the full assembly is often faster and prevents a second repair if the latch is also worn.
Why did my trunk lock stop working after a dead battery on my Bmw 335I Gt Xdrive?
A dead or disconnected battery can reset or disable the body control module settings that govern the trunk actuator. Start by reprogramming your key fob according to the owner's manual. If the fob works but the actuator still does not respond, the actuator motor or its wiring may have failed independently of the battery event.
Will a replacement trunk lock come with a key that matches my existing ignition key on the Bmw 335I Gt Xdrive?
Aftermarket trunk lock cylinders are almost never pre-cut to match your existing ignition key. Most arrive either uncut or keyed to a generic code. A locksmith can re-key a replacement cylinder to match your current key for a small fee, which is worth doing so you do not have to carry two separate keys for the Bmw 335I Gt Xdrive.
Is it safe to drive my Bmw 335I Gt Xdrive if the trunk lock is broken and the lid won't stay shut?
No. A trunk lid that cannot latch is a hazard — it can fly open at speed, block your rear view, and in a rear-end collision it behaves unpredictably. Secure the lid temporarily with a cargo strap or bungee cord as a short-term fix, but replace the latch or lock as soon as possible to restore safe operation.
How long does a trunk lock typically last, and what causes it to fail early on a Bmw 335I Gt Xdrive?
Trunk lock mechanisms are generally designed to last the life of the vehicle under normal use, but several factors shorten that lifespan. Exposure to road salt and moisture corrodes the cylinder and latch. Forcing a stiff key, slamming the lid, or a prior rear-end impact can bend internal components. Actuator motors wear out over many thousands of cycles.
