Describe the incident before choosing replacement parts
Say whether it was a brief splash, immersion or machine wash, and when it happened. Mention a physical drop, an opened shell and which functions stopped working. Repeated button presses are not needed to demonstrate a fault.
The reviewed Hyundai instructions warn of key-circuit damage from moisture and heat. Appropriate treatment depends on the particular key condition; drying alone is not a promised repair.
What has already been done to the key?
Report battery replacement, shell disassembly, cleaning products or heating. This information matters for inspection. Avoid improvised heating or moving parts to a different shell without understanding their condition.
Keep the components you have. If you do not know which piece belongs to the key, photograph them together and ask how to proceed with the enquiry.
A spare key and the functions that remain
Mention any dry, working spare. Describe its functions so a key problem can be distinguished from other vehicle behaviour. Compare the same operations rather than simply saying the spare works.
If the wet key still performs some functions, specify which ones. Temporary response does not establish that it is sound. If there is no spare and the car cannot be used, explain that this is your only key.
Inspection, repair or a replacement key?
Inspection and treatment options depend on the damage and specific part. Before ordering a replacement, clarify what you have and what the service can include. A wet key does not have one universal price or outcome.
If a new key is required, ask whether the quote includes a blade, starting recognition and remote or proximity functions. Even with a known incident, replacement compatibility is checked against the vehicle.
After you can use the vehicle again
Test the agreed functions with the key and vehicle together. Keep the work and warranty details. If only one usable key remains, enquire about a spare so a fault in that key does not leave you without access.
For a compatibility enquiry, send the model, year and incident description. We can check what needs to be available and whether the appropriate service can be performed where the vehicle is parked.
