DS5 Remote Locking and Starting Issues

Sounds familiar. I've got a Citroen DS5, year unknown, and had similar central locking and starting issues. It could be the antenna, or something else. Have you checked for any obvious damage to the antenna mount?

Thanks. When you had similar problems, was it the antenna itself, or just the mount or connection? Any details?

I can't say if your problem is identical, but the symptoms seem similar. In my case, it was a faulty connection at the antenna. I'd recommend getting it checked at a workshop. Better safe than sorry.

Thanks for the advice. I had the antenna connection checked. A cable was defective. The repair, parts and labor, cost 95€. Everything works now.
