Matrix remote locking issue

Alright, I'm pulling my hair out here. My 2005 Hyundai Matrix diesel is throwing a fit. Mileage is at 133683 km. It's showing an error in the memory related to the bumper antenna. Now, the remote central locking is completely useless, and I can't even start the darn thing without the key physically in the ignition. Anyone seen anything like this? I suspect a dodgy connection, but where do I even start?

Summary of the thread

A 2005 Hyundai Matrix diesel is experiencing issues with remote central locking and starting, linked to an error in the bumper antenna circuit. The problem is likely due to a defective cable or plug connection, possibly a corroded connector near the antenna. The suggested solution is to have a workshop inspect and repair the connection, which resolved the issue for another owner with a similar problem.

I had very similar symptoms with my Matrix. It drove me crazy for a while. Was the error message specifically pointing to the antenna mount or vehicle antenna, or was it more generic?

The error message is pretty vague, just mentions the bumper antenna circuit. Did yours completely disable the remote locking and starting, or was it intermittent?

Yes, it completely disabled the remote functions. Based on your symptoms and the error code, it's highly likely a defective cable or plug connection. I ended up taking mine to a workshop, and they traced it to a corroded connector near the antenna. Might be worth having them take a look, unless you're comfortable chasing wires yourself.

Thanks! Sounds like I'm heading to the workshop. I appreciate the insight. They located the issue at the antenna connection, just like you said. 95€ later, it's fixed!
