Yanhua Btool BCP Key Cutting Kits provides a professional and precise solution for BMW BCP key disassembly, allowing technicians to open the key shell accurately while protecting the internal PCB.
This guide explains how to disassemble the BMW BCP key inner shell step by step using Yanhua Btool BCP Key Cutting Kits.
Step 1 – Install the BMW BCP Key in the Yanhua Btool Fixture
Start by preparing the Yanhua Btool BCP Key Cutting Kits and place the BMW BCP key into the dedicated fixture.
Open the key clip and align the BMW logo button with the clip’s inner column.
Then position the key carefully so that the limiting hole matches the limiting pin on the fixture.
After the key is properly aligned, close the clip and tighten it securely. This ensures that the key remains stable during the cutting process.
Step 2 – Begin Cutting the Ultrasonic Welding Area
Once the key is secured in the Yanhua Btool cutting fixture, push the clip into the base plate and tighten the nut.
The tool will expose the ultrasonic welding seam on the BMW BCP key shell, the section that needs to be cut.
Start cutting from the far right side of the key shell.
Align the blade with the welding seam and insert it into the gap. Gently tap the blade with a hammer to start cutting along the seam.
Continue until the blade reaches the locking notch.
Step 3 – Continue Cutting Along the Welding Seam
Next, install the blade into the blade clamp and tilt it at approximately 20 degrees.
Align the blade carefully with the welding seam and strike it lightly again to continue separating the shell. This controlled cutting method ensures the shell opens without cracking or damaging the internal structure.
Using Yanhua Btool BCP Key Cutting Kits allows precise control during this stage of the BMW BCP key disassembly process.
Step 4 – Use a Scalpel for Precision Cutting
When the blade reaches the groove of the fixture, switch to a scalpel for more precise cutting.
Insert the scalpel vertically into the groove and move it horizontally so the back of the blade touches the bevel. Continue tapping gently until the blade penetrates the bottom of the shell.
This step helps separate the remaining welded sections cleanly.
Step 5 – Cut the Front Sections of the BMW BCP Key
After opening the side welding seam, proceed to the front section of the BMW BCP key inner shell.
Follow the marked cutting areas and begin with the first three sections.
Insert the blade at a 20-degree angle, align it with the welding seam, and gently tap it with a hammer.
Repeat the process until the cutting reaches the third marked section.
Step 6 – Pry Open the BMW BCP Key Shell
After the cutting steps are completed, use a pry tool to open the shell.
Insert the pry tool into the groove on the back of the key and apply pressure alternately from the left and right sides. This will gradually separate the welded seams.
Continue prying carefully until the BMW BCP key inner shell is fully opened.
Step 7 – Remove the Internal PCB Board
Once the shell is separated, carefully remove the internal PCB board.
If the cutting steps were performed correctly using Yanhua Btool BCP Key Cutting Kits, the PCB will remain intact and undamaged.
At this stage, the BMW BCP key disassembly process is complete, and technicians can proceed with chip replacement, repair, or programming.
Opening a BMW BCP key inner shell requires the correct tools and techniques. With Yanhua Btool BCP Key Cutting Kits, technicians can safely perform BMW BCP key disassembly while protecting the internal electronics.
