Step-by-Step Guide to Installing Galaxy 20 Digital Locks in Iranian Homes

Installing a digital lock can dramatically improve convenience and security—especially in Iranian homes where door types, local wiring habits, and common hardware standards can vary from one building to another. This step-by-step guide walks you through how to install the Galaxy 20 digital lock safely and correctly, with practical tips tailored for typical doors found in Iran. If you’re upgrading from a traditional key lock, you’ll also learn what to check before drilling or changing the mortise.

Tools needed to install a Galaxy 20 digital lock

Why Choose Galaxy 20 Digital Locks for Iranian Homes?

The Galaxy 20 digital lock is popular because it offers a modern access experience while improving everyday security. It can reduce the risk of lost keys, support controlled access for family members, and make entry easier for apartments and villas alike.

Common reasons homeowners upgrade:

Easier access (PIN, card, or fingerprint depending on the model configuration)
Better control over who can enter and when
Reduced reliance on physical keys
A cleaner, modern look that fits updated doors

Before You Start: Check Door Compatibility

Before installation, verify that your door can support a digital lock. In Iran, doors typically fall into a few categories: wooden interior doors, reinforced apartment doors, and metal security doors.

Installing the mortise for Galaxy 20 digital lock

Measure these key points

Door thickness: Measure the door thickness with a tape measure.
Backset: Distance from the door edge to the center of the lock hole.
Mortise space: Ensure there is enough internal space for the lock body.
Door alignment: A sagging door can cause latch friction and poor lock performance.

If your door has a very old or non-standard mortise, you may need minor modifications or a compatible mortise replacement.

Tools You’ll Need

Prepare tools before starting so the process is smooth:

Luxury cylinder type lock body

Measuring tape and marker
Drill + drill bits (wood/metal depending on door)
Screwdriver set
Chisel (for wooden doors if adjustments are needed)
Allen key (if included with lock kit)
Level (recommended)
Safety glasses

Step-by-Step Installation of Galaxy 20 Digital Locks

Installing the strike plate for Galaxy 20 digital lock alignment

Step 1: Unbox and verify all parts

Lay all components on a clean surface. Typically, you’ll have:

Front panel (keypad/fingerprint reader)
Back panel (battery compartment)
Mortise/lock body
Strike plate
Screws and mounting hardware
User manual + template (if provided)

Tip: Confirm the lock powers on before full installation (if the batteries are included).

Step 2: Remove the existing lock

Open the door and keep it stable.
Unscrew the handles and remove the existing cylinder/mortise.
Keep the old parts aside in case you need measurements or backup.

If the old lock is heavily worn or the hole edges are damaged, it’s worth reinforcing the area before installing the digital lock.

Step 3: Mark drilling points using the template

Most Galaxy 20 kits include a drilling template. If you don’t have one:

Align the lock body position on the door edge
Mark the center points for the spindle, screws, and wiring path (if applicable)

This step matters a lot. Incorrect marking is the most common cause of misalignment later.

Step 4: Install or replace the mortise lock body

Insert the mortise into the door edge.
Check if it sits flush. If not, lightly chisel the edges for a clean fit (wooden doors).
Screw it in place, but don’t overtighten yet.

Make sure the latch direction matches the door swing (left-hand or right-hand opening). If your model supports latch reversal, adjust it now.

Step 5: Drill required holes and route the cable (if applicable)

Drill carefully at the marked points.
If the lock has an internal cable between front and back panels, route it through the door as instructed.
Avoid sharp edges around the cable path—this prevents future cable damage.

For metal doors common in Iran, use proper metal bits and drill slowly to avoid overheating.

Step 6: Mount the front panel

Position the front panel on the exterior side of the door.
Ensure the spindle aligns cleanly with the mortise mechanism.
Hold it steady while you connect any internal cable.

A misaligned spindle can cause stiff handle movement or failed locking.

Step 7: Mount the back panel and secure screws

Attach the back panel from inside the home.
Connect the cable (if present).
Tighten mounting screws evenly.

Do not overtighten. Too much pressure can warp the panels and reduce sensor accuracy.

Step 8: Install the strike plate on the frame

This is a crucial step for performance.

Close the door and test latch alignment.
Mark the latch contact point on the door frame.
Install the strike plate so the latch enters smoothly.

If the latch hits the frame, you’ll get friction, incomplete locking, or “door not closed” warnings in some models.

Step 9: Insert batteries and run initial setup

Install the batteries in the back panel.
Power on the lock.
Set the admin/master code first.
Add user access methods (PIN, card, fingerprint as supported).

Important: Keep the master code private and store it securely.

Step 10: Test all functions (don’t skip)

Test thoroughly before considering the job done:

Lock/unlock via keypad/fingerprint/card
Manual key override (if available)
Handle movement (smooth, no stiffness)
Auto-lock function (if enabled)
Door closing detection (if present)

If anything feels tight, fix alignment now—small adjustments early prevent long-term issues.

Common Installation Issues in Iranian Homes (and Fixes)

Door frame misalignment

Common in older buildings. Solution:

Adjust strike plate position
Reinforce frame area if needed

Mortise not matching standard cutout

Some doors have custom mortises. Solution:

Use a compatible mortise model
Minor door-edge modification

Weak door material around lock area

Seen in older wooden doors. Solution:

Reinforce the lock area using proper plates or wood filler before mounting

Maintenance Tips After Installation

Replace batteries on a schedule (don’t wait for full depletion)
Clean the keypad/fingerprint area gently (no harsh chemicals)
Re-check screws after 2–3 weeks of usage
Keep the door properly aligned to prevent friction damage

Conclusion

Installing Galaxy 20 digital locks in Iranian homes is straightforward when you measure correctly, align the mortise and strike plate carefully, and test everything before final tightening. The biggest success factor is not speed—it’s precision. If you’re unsure about drilling into a security door or adjusting a mortise, professional installation can save time and prevent door damage.
