Removing a side mirror cover on a Hyundai i20 without snapping brittle plastic clips requires patience and proper technique. Whether you're replacing a cracked cap, painting a custom housing, or fixing a loose indicator light, you don't need an expensive trip to the mechanic. With a few simple plastic trim tools and 20 minutes of spare time, you can safely detach the housing.
The main challenge lies in releasing the hidden internal locking tabs without cracking the painted exterior shell. Factory clips are engineered for permanent assembly, meaning they lock tightly and resist simple pulling. This guide walks you through the exact process to protect your paint, avoid broken clips, and complete the job cleanly.
Tools and Preparation Needed
Before you touch the car, gather the right equipment to prevent accidental cosmetic damage. Using metal screwdrivers directly on painted plastic parts will gouge the surface instantly.
- Plastic trim removal wedges: Use soft nylon or plastic pry tools to distribute pressure evenly.
- Small flathead screwdriver: Needed only for pushing deep interior release tabs.
- Masking tape: Wrap this around the edges of the mirror housing to protect surrounding paint if a tool slips.
- Microfiber towel: Place this underneath the workspace to catch small screws or parts.
- Work light or flashlight: Crucial for spotting dark internal locking clips.
Park your Hyundai i20 on a flat surface, engage the parking brake, and switch off the ignition. If your car features power-folding mirrors, fold them inward to gain a better working angle. You can consult official specifications on the Hyundai Motor Company portal if you need vehicle-specific generation diagrams.
Step 1: Detach the Mirror Glass Safely
You cannot reach the primary retaining clips from the outside without first removing the glass. This step makes many DIYers nervous, but the glass snaps onto a central circular actuator mount rather than bolting down.
Adjust the mirror glass electronically so that the inner edge tilts inward as far as possible, creating a gap on the outer edge. Carefully insert a flat plastic trim tool behind the glass plate. Apply gentle, even pressure outward while using your fingers to support the glass face.
The clips will release with a sharp pop. Don't pull it completely away yet, because heated mirrors or auto-dimming variants have electrical wires attached to the back. Unplug these spade terminals carefully and set the glass aside on a soft cloth.
Step 2: Access and Release Internal Housing Screws
With the mirror glass removed, you are looking directly at the internal adjustment motor and plastic chassis. Depending on your specific model year, you will see a central mounting screw or multiple positioning clips holding the inner assembly together.
Locate the primary small screw or clip securing the actuator base. Unscrew it carefully and place it where it won't roll away. Some model variants require you to push outward on tiny side tabs surrounding the motor housing to shift the inner frame.
Once the inner obstruction is loosened or removed, you gain a clear line of sight to the backside of the outer mirror cover. This rear view exposes the stubborn locking tangs that keep the cap locked tightly to the skeletal frame.
Step 3: Pop Off the Outer Mirror Cover
Now that the internal obstacles are cleared, you can focus on the painted outer cap. Factory covers rely on three or four interlocking plastic clips along the top, bottom, and outer edge near the turn signal repeater.
Insert a thin plastic wedge into the seam near the outer indicator light. Gently pry outward to disengage the first locking tab. As soon as one corner pops free, wedge a second trim tool into the gap so it doesn't snap back into place.
Work your way systematically around the perimeter, sliding additional trim tools into each newly opened gap. Apply firm, steady pressure outward until the remaining clips release. The cover will separate from the assembly. Watch out, as older plastic can release suddenly under spring tension.
Common Mistakes to Avoid
Rushing through trim removal is the fastest way to turn a simple ten-minute task into an expensive replacement job. Keep these pitfalls in mind:
- Skipping glass removal: Trying to pry the outer cap off from the front without removing the glass first will snap every single retention tab on the cover.
- Using metal tools: Metal screwdrivers act as levers that crack plastic housing and ruin clear coat paint finishes. Stick exclusively to nylon trim tools.
- Working in freezing temperatures: Cold weather makes automotive plastics brittle. If it's winter, perform the work inside a warm garage or use a hair dryer to gently warm up the plastic clips beforehand.
- Pulling wiring too hard: When unplugging mirror indicators or heating elements, pull on the plastic connector plugs rather than yank on the thin copper wires.

Frequently Asked Questions
Can I remove the Hyundai i20 mirror cover without taking off the glass?
No. The primary clips securing the cap are locked from the inside. Forcing the cover off from the exterior without releasing those interior tabs will break the plastic locking fingers permanently.
What should I do if a plastic clip breaks during removal?
A single broken clip rarely ruins the entire job. If three out of four clips remain intact, the cover will still snap back securely. If you're worried about wind vibration, add a tiny drop of automotive-safe plastic adhesive or double-sided trim tape inside the seam before reassembly.
How do I put the new mirror cover back on?
Reassembly is simply the reverse process. Align the new cover with the housing pins, check that all edges match up with the frame, and push firmly until you hear a series of sharp snaps. Reinstall the actuator screws, plug the heating or signal wires back into the glass, and press the glass gently onto its central mount.
