2021-2022 Hyundai Anti-Theft Ignition Cylinder Protector TSB

Hyundai has released Technical Service Bulletin (TSB) 25-01-089H, identified as Customer Satisfaction Campaign P33, to provide a security upgrade for a range of its vehicles. This campaign, dated December 2025, focuses on installing a key cylinder reinforcement protector assembly and anti-theft decals. This measure aims to bolster the security of affected models against potential theft.

The Hyundai anti-theft ignition cylinder protector is designed to reinforce the ignition system, making it more difficult for unauthorized individuals to start the vehicle. Additionally, anti-theft decals are applied to the windows, serving as a visual deterrent.

What's Being Addressed

This TSB 25-01-089H addresses a vulnerability in the ignition system of certain Hyundai vehicles that could make them susceptible to theft. The solution involves a two-part approach: a physical reinforcement of the ignition cylinder and the application of highly visible anti-theft decals.

The ignition cylinder protector is a robust component that encases the existing ignition cylinder, adding a layer of physical security. The anti-theft decals, featuring the message "THIS VEHICLE EQUIPPED WITH HYUNDAI ANTI-THEFT PROTECTION", are intended to inform potential thieves that the vehicle is equipped with enhanced security measures. This campaign applies specifically to vehicles NOT equipped with an immobilizer or a START/STOP ignition button.

Important Warnings for Owners

Owners should be aware of several critical points regarding this service procedure:

• Customer Request Only: This procedure is performed ONLY upon customer request. Hyundai is NOT notifying consumers for this campaign; owners must proactively ask their dealership for the service.
• Ignition Key Ring Light Removal: If your vehicle is equipped with an ignition key ring light, it will be removed during the installation of the ignition cylinder protector. The dealership is required to inform you of this removal prior to starting the repair.
• Epoxy Application Restrictions: Technicians are explicitly warned to "Be careful to NOT apply any epoxy inside the key mechanism or near electrical area" to prevent damage to critical components. This ensures the proper function of the ignition system post-installation.
• Decal Handling: When installing the anti-theft decals, technicians are instructed to "Be careful NOT to touch the adhesive side of the decal as fingerprints will reduce the bonding strength to the window glass."
• Window Tinting: If your vehicle's windows are tinted with a non-legal shade, the customer must be informed of the "possible poor visibility of the anti-theft decals."
• Warranty Exclusions: This coverage does NOT apply to components damaged due to theft or attempted theft. Additionally, any repair where the Ignition Cylinder Protector affects the repair time or cost for other required parts/labor is subject to review before being covered under goodwill; a Prior Authorization (PA) request is necessary in such cases.
• VIN Capture: For older vehicles, the 'AUTO VIN' function in the STUI system may "NOT operate normally"; in such cases, the VIN must be input manually "before capturing pictures with STUI."

Detailed Repair Procedure

The service procedure for installing the Hyundai anti-theft ignition cylinder protector and decals involves several precise steps, as outlined in TSB 25-01-089H:

Epoxy Preparation

The procedure begins with preparing the JB Weld Steel Reinforced Epoxy Product No. 50165. This dark grey epoxy has a set time of 4-6 hours and should be mixed first to allow for slight thickening, which aids application. The syringe kit can be used for up to four vehicles.

1. Mark the epoxy syringe handle with three equal marks to divide the epoxy into four sections.
2. Twist the cap counterclockwise and remove it.
3. Squeeze 1/4 (up to the first mark) of the epoxy onto a clean, disposable surface like paper or cardboard.
4. Use a disposable plastic or wooden stick to thoroughly mix the epoxy until it achieves a consistent gray color.
5. Reinstall the cap by twisting clockwise to lock it in place.

Ignition Cylinder Access and Disassembly

Accessing the ignition cylinder requires careful removal of surrounding trim components.

1. Using a small flathead screwdriver, carefully pry upward to disengage the upper steering cover.
2. Remove the screws holding the lower cover. This involves turning the steering wheel to the left to remove one screw, then turning it to the right to remove a second screw. A third screw from under the cover is also removed.
3. Remove the bottom steering wheel cover.
4. To remove the key portion of the ignition cylinder, turn the key to the ACC position.
5. Use a small tool, such as an Allen wrench, to depress the locking pin.
6. While depressing the locking pin, gently wiggle and pull the key portion away from the ignition cylinder assembly.
7. Disconnect the key sense connector to fully remove the key portion.

Key Ring Removal and Management

Depending on the vehicle's configuration, the ignition key ring may need to be removed.

1. Both non-illuminated and illuminated ignition key rings will be removed and discarded.
2. For non-illuminated key rings, pry it away from the key ignition cylinder with a small flathead screwdriver.
3. For illuminated key rings, remove the screw and then detach the ring from the ignition cylinder.
4. If an illuminated key ring is removed, cut the harness wires. Cut one wire shorter than the other to prevent cross-shorting.
5. Use electrical tape to wrap the cut wires onto the harness.
6. Some models may require installing a non-illuminated key ring from the parts kit to fill the gap created by the removal.

Epoxy Application for Protector

Epoxy is strategically applied to secure the new protector.

1. Apply a sufficient amount of epoxy around the inside ring of the cylinder.
2. Apply epoxy around both the cylinder body (A) and key cylinder (B), and specifically over the locking pin area (C).
3. Apply epoxy over the area where the protector locking bracket will sit.
4. NOTICE: It is critical to "NOT apply any epoxy inside the key mechanism or near electrical area."

Protector Installation and Reassembly

After epoxy application, the protector is installed and components are reassembled.

1. Insert the key cylinder back into its body.
2. Insert the ignition sleeve and apply epoxy to the locking tab area.
3. Install the sleeve screws and tighten them until their heads are broken OFF.
4. Wipe off any excess epoxy residue with a cloth.
5. Reinstall all removed trim panels and other components in reverse order of removal.
6. Verify that the steering wheel and ignition cylinder are operating normally.

Anti-Theft Decal Installation

Anti-theft decals are installed on the vehicle's windows.

1. Print the anti-theft decal installation template (found on the last page of the TSB).
2. Fold the template from the bottom upward along the solid line and cut out the two indicated rectangles.
3. Roll both the front driver and passenger windows to their uppermost closed position.
4. If an existing anti-theft decal with the verbiage "HYUNDAI ANTI-THEFT LOGIC" is present, remove it and replace it with the new decal featuring "HYUNDAI ANTI-THEFT PROTECTION."
5. Clean the inside lower left corner of the front driver's side window and the lower right corner of the front passenger's side window with rubbing alcohol and a clean rag.
6. Align the template edge approximately 1/4 inch next to any existing label's/decal's edge.
7. Secure the template onto the glass and door panel using masking tape.
8. Tear or cut two anti-theft decals (NP002-SC9A5) from the roll.
9. Without touching the adhesive side, carefully peel back the paper backing halfway and align the decal within the cut-out rectangle of the template.
10. Firmly press the decal onto the window glass with your thumb.
11. Remove the template and continue pressing down on the decal to ensure no visible bubbles.
12. Repeat steps 5-10 for the other front window.
13. If the customer requests, two additional decals can be installed on the rear windows, positioned next to any existing decals.

Digital Documentation for Claim Submission

For warranty claim submission, specific photos are required:

1. Take a photo of the installed Hyundai anti-theft ignition cylinder protector using the STUI camera function.
2. Take photos of both anti-theft decals on the driver and passenger side front windows using the STUI camera function.
3. If the STUI camera function is NOT used, write the last 6 digits of the VIN and the repair date on a piece of paper and include it in the photo.
4. Digital documentation pictures are NOT required for rear window anti-theft decal installation.
