ERMWALR Tailgate Lock for BMW 1 Series F20/F21 – OEM-Style Boot Latch Actuator (51247248075 / 7248075)
Product description
What it is
This ERMWALR tailgate lock is designed to match the original equipment design for BMW 1 Series models in the F20 and F21 family, including LCI variants, as well as certain i3 configurations. It’s a replacement boot lid lock aimed at restoring reliable operation of the tailgate mechanism without the complexity of a DIY re-engineer.
What problem it solves
If your tailgate won’t latch, intermittently opens, or feels loose, a worn or damaged lock can compromise both convenience and security. This unit offers a straightforward swap that integrates with the vehicle’s existing design, helping you restore a smooth boot operation with minimal fuss.
Compatibility and verification
The product is stated to fit: BMW 1 Series F20 (07/2010 — 02/2015), F20 LCI (05/2014 — 08/2018), F21 (07/2010 — 02/2015), F21 LCI (05/2014 — 08/2018), and certain i3 I01 generations (01/2013 — 10/2017) including I01 LCI (01/2017 — 08/2018). It lists OEM part numbers 51247248075, 51 24 7 248 075, 7248075. Before ordering, it’s prudent to double‑check the exact OEM number on your current lock to avoid a mismatch.
Build quality and material emphasis
Described as crafted from premium materials, the tailgate lock is positioned to offer durability and resistance to breakage in daily use. While the description highlights reliability, note that real‑world performance will still depend on overall tailgate wear, mounting hardware condition, and the electrical system in your vehicle.
Installation considerations
The design is described as requiring no complex installation—simply swap out the old lock for the new unit. In practice, you’ll typically need basic hand tools and to ensure the battery is disconnected if accessing wiring. If you’re not confident with boot‑lid hardware work, consider seeking professional assistance to avoid misalignment or wiring issues.
What’s good about it
• OEM‑style compatibility helps maintain original fit and appearance. • The claimed premium materials suggest better longevity than a very low‑cost substitute. • Straightforward swap could save time versus a more involved diagnostic repair.
Potential limitations
• The claim of “no complex installation” should be tempered with the reality that boot latch systems can involve multiple connecting rods and sensor wiring. If the mounting points or wiring harness differ from your exact model year, you may encounter fitment variances. • It is not a universal replacement, correct OEM number and Vehicle Identification is essential.
Who it’s for
This is likely a reasonable option for owners who want an OEM‑style replacement to restore normal boot operation on affected F20/F21 1 Series models (and eligible i3 variants), especially if they prefer a block‑style swap over diagnosing more complex tailgate faults.
Who it isn’t for
If your tailgate issue stems from other components (e.g., latch alignment, hydraulic struts, or central locking electronics), this part alone may not resolve the problem. It’s also not advisable for those who cannot verify exact OEM compatibility or who expect performance beyond standard OEM specs.
When it makes sense to buy
Consider this replacement if your BMW’s boot lid no longer latches securely, you notice intermittent operation, or you want to restore factory‑level function after testing for lock wear. Verification of the OEM number and model range is key before purchase.
Before you buy
– Confirm the exact vehicle model and year range matches the listed compatibility. – Check the OEM part numbers on your current lock to ensure a correct match (51247248075 or 7248075 variants). – Assess the condition of related tailgate components, a worn striker or wiring fault may also contribute to latch problems. – If in doubt, consult a professional to confirm that the failure is indeed the lock and not another tailgate subsystem.
Practical usage example
Imagine you reach for the boot and it closes with a satisfying click instead of needing a second attempt or a manual nudge. Replacing the lock is most straightforward when you’ve recently inspected the surrounding tailgate linkage and found the latch mechanism itself to be the root cause rather than the actuator wiring alone.
Practical alternatives and choice context
If you prioritise factory compatibility and a straightforward fix, this OEM‑style replacement is a sensible route. In contrast, if you’re looking for a cheaper, non‑OEM component, a generic latch substitute may seem tempting, but it risks fitment issues or inconsistent operation. On the other hand, if you’re diagnosing broader tailgate electronics, a professional assessment could help pinpoint whether the lock or other subsystems are at fault.
Decision: Is it worth it?
It makes sense to buy if you’ve confirmed the OEM number matches and the problem is confined to the tailgate lock mechanism. It may not be the best option if you’re uncertain about compatibility or if the fault lies elsewhere in the boot system.
FAQ
- How do I verify compatibility with my BMW 1 Series? Check the vehicle’s OEM part number for the tailgate lock and compare with 51247248075 or 7248075.
- Will this fix a jammed boot latch? If the issue is due to a worn lock, replacement can restore normal operation, but other boot components should be inspected.
- Is installation difficult? The issuer describes it as straightforward, but ensure to disconnect the battery and follow safe mounting practices to avoid misalignment or wiring damage.
