Yeah this is car related but I stand a better chance of getting this sorted on here than anywhere.
So ... I have a 2007 Chrysler 300c CRD.
The EGR valve gasket was leaking oil so I got a local garage to sort that.
I picked the car up this afternoon and I have gained a noise.
The ignition key is the original-style metal key (up to about '08-'09 maybe?) and not the plastic Mercedes plug-in key I had in my '10.
If I put the ignition key in, after 4-5 seconds there is a harsh sounding electronic beeping noise. Maybe 6-7 beeps in a second or two. Rapid.
I tried starting straight away or just put the key in and not starting. Same noise.
It's NOT the bong bong of the seatbelt. The bloke in the garage suggested that 'fix' but all that has achieved is to turn back ON the bong bong of the seatbelt!!

Anyone have a Chrysler / Dodge that has done the same?
This is my third 300c. Never had this before.
My first thought was maybe the battery in the key is low. The transponder thing getting low. I don't know.
Internet searches all seem to turn up the seatbelt noise. It's not that.
I've had enough American cars to know the usual 'key is in', 'door is open', 'your hair looks nice today' noises.
Car drives fine. Better in fact than before (I assume the sensor on the EGR valve is sending the right signals now the leak is fixed?).
I can't just carry on driving it like it is just because it runs ok, modern cars don't make electronic sounds for no reason.
Anyway, I'm looking to sell it as I've seen a nice Caddy locally that I like the look of ...
Thanks in advance
