FAQ
TL;DR: For Hyundai i30 FD remotes, users report pairing 433 MHz HA‑T005 units via the Cascade “Code saving” function, but “Only G‑scan 2 will overwhelm.” [Elektroda, Aleksander_01, post #16942072]
Why it matters: This FAQ helps DIYers decide when Cascade and a KKL/CAN cable are enough and when a pro scanner is required for success and security.
Quick Facts
- Remote spec discussed: 433 MHz HA‑T005 for central locking on i30 FD. [Elektroda, _no_rulrs_, post #16900636]
- Tool callout: “Only G‑scan 2 will overwhelm” for this job, per a senior member. [Elektroda, Aleksander_01, post #16942072]
- Cascade “Code saving” pairs the central-locking remote; it does not program the immobilizer. [Elektroda, rob4028, post #16920312]
- KKL/CAN-style cables exist, but confirm CAN capability before attempting coding. [Elektroda, coperfild, post #16912240]
- IMMO/key coding needs the immobilizer code; a basic KKL cable alone is insufficient. [Elektroda, rob4028, post #17013221]
Can I code an AliExpress 433 MHz HA‑T005 remote to a Hyundai i30 FD with Cascade?
Yes, forum users reference pairing through Cascade’s “Code saving” function for central locking. This process pairs the remote to the central locking module only. It does not add an immobilizer transponder to start the engine. Plan your workflow around remote pairing versus IMMO key programming, which are separate tasks. “Code saving is used for coding the central-locking pilot and that’s all.” [Elektroda, rob4028, post #16920312]
Which scan tool is most often recommended in the thread for this job?
Members state that “Only G‑scan 2 will overwhelm,” suggesting that a professional G‑scan 2 can complete the pairing when simpler interfaces struggle. If you lack G‑scan 2 access, consider a workshop equipped with this tool to avoid repeated failures and save time. This aligns with the thread’s strongest single-tool recommendation. [Elektroda, Aleksander_01, post #16942072]
Is the immobilizer affected when I pair the central locking remote?
No. Pairing the central locking remote does not program the immobilizer. Your car will not start with an unprogrammed transponder even if the remote locks and unlocks doors. Treat IMMO key coding as a separate step requiring the immobilizer PIN and appropriate tooling. “You do not fire your car” after using Code saving. [Elektroda, rob4028, post #16920312]
Does a VAG KKL USB cable work for i30 FD key coding?
A KKL cable may communicate with some modules, but it is not sufficient for immobilizer key programming by itself. Key coding requires the immobilizer code and compatible software or a pro scan tool. Users who bought KKL hardware still needed the IMMO PIN to proceed. [Elektroda, rob4028, post #17013221]
What does the Cascade “Code saving” option actually do?
In this context, Code saving enters a pairing mode for the central-locking receiver. With the function active, you press Enter in software and then press the remote’s unlock button to store the code. This links the 433 MHz remote to the central unit but does not touch IMMO. [Elektroda, coperfild, post #16919872]
How do I pair the central locking remote using Cascade? (3 steps)
- Connect your CAN-capable interface and open Cascade’s Code saving tab.
- Press Enter to activate learning on the target module.
- Press the remote’s unlock/open button to store the code. [Elektroda, coperfild, post #16919872]
What if Cascade connects but the remote still won’t program?
Confirm your interface supports CAN and that the remote is the correct 433 MHz type. If pairing still fails, escalate to a shop with G‑scan 2, the thread’s recommended tool for this platform. Hardware limitations are a common cause of unsuccessful attempts. [Elektroda, Aleksander_01, post #16942072]
Will coding an AliExpress remote let my 2008 i30 FD start?
No. A paired remote only controls central locking. To start the car, you need a key with a matched transponder or a cloned chip. The thread author planned to clone the transponder from the original key, which is a separate process from remote pairing. [Elektroda, _norulrs, post #16923526]
What is the CAN bus, and why does my cable need it?
The CAN bus is the car’s controller network connecting modules like the central lock ECU. Your interface must support CAN to access the correct module for pairing on many vehicles. Members explicitly ask whether the user has KKL or CAN-capable hardware before proceeding. [Elektroda, coperfild, post #16912240]
I have a 2007–2008 i30 FD; is IMMO access straightforward?
Not always. One member noted that IMMO access for that year was “no longer valid,” implying tighter access or changed procedures. Expect to retrieve the immobilizer code or use pro equipment if DIY paths fail. Treat IMMO as a separate, more restricted workflow. [Elektroda, rob4028, post #16940686]
Do I need the immobilizer code to add a new key without a remote?
Yes. A member trying to add a non-remote key still required the immobilizer code to complete programming. Without the PIN and proper tooling, DIY attempts stall even if diagnostics connect. Plan for code retrieval or professional service. [Elektroda, rob4028, post #17013221]
What frequency remote should I buy for i30 FD central locking?
The discussion revolves around a 433 MHz HA‑T005 remote sourced from AliExpress for central locking. Ensure your replacement matches this frequency and form factor. Mismatched frequency remotes will not pair or function, even if procedures are correct. [Elektroda, _norulrs, post #16900636]
Is Cascade the best choice, or should I go straight to a pro tool?
Cascade can pair remotes via Code saving when hardware and vehicle support align. However, the thread’s clear recommendation is G‑scan 2 if you meet connection errors or incomplete menus. “Only G‑scan 2 will overwhelm,” summarizing the pro-tool advantage. [Elektroda, Aleksander_01, post #16942072]
Edge case: Why would someone ask for the IMMO code just to adapt a remote?
They shouldn’t. One user questioned why IMMO code would be needed to adapt only the central-locking remote. Remote pairing and immobilizer programming are separate. Confusing the two leads to unnecessary hurdles and costs. Keep tasks distinct to avoid delays. [Elektroda, revolt2, post #18886186]
Can I clone the transponder from my original key to a new one?
Yes, the thread author planned to clone the transponder “tablet” from the original remote for about 100 PLN. Cloning duplicates the IMMO identity, allowing the new key to start the car without dealer coding. Remote pairing remains a separate step. [Elektroda, _norulrs, post #16923526]
What’s a quick success checklist before I start?
Verify: 1) Correct 433 MHz HA‑T005 remote; 2) CAN-capable interface; 3) Cascade Code saving access; 4) G‑scan 2 backup plan. Following this cuts retries and tool-swaps. When in doubt, hand it to a shop with G‑scan 2. [Elektroda, Aleksander_01, post #16942072]
