Rubbish, went to get it cut and broke because of poor quality metal… avoid!

I got this because I'm restoring an old e46 325ci. The people complaining about the buttons being stiff are silly. The buttons are STIFFER than the OEM key, but they're perfectly fictional and after a day of using it, I don't even think about it being stiffer.

I will use the key blade and battery but I am less convinced by the plastic fob moulding. My main concern is the buttons are quite stiff in particular the boot release button. The whole fob centre seems to have to flex in order to get the button into the depressed position. I suspect the plastic material less flexible that the oem item although it's hard to compare them as the texture and feel is quite different because of the fresh rough feel of the graining of the new item as a pose to the smooth worn old key. I will be interested to read further reviews to see how others managed with the button functionality.

Key very well made ,just read recently chip is there ,frequency is right. Let's believe will work perfectly. Thanks so much

The remote is working & 2 min job to programme it to the car. The transponder part has to be programme by a professional locksmith or dealer but the remote part working perfectly 👌 thanks

The blade is unsuitable to cut. Spoke to a car key cutter and they can't do it due to the shape.

At first sight, the replacement fob case looked suitable as a backup. When I opened the plastic bag and tried to press the buttons, I was disappointed that the buttons were hard to press. There isn’t the flexibility that is expected to activate the switch inside. Compared to the original, it is about four times harder to press even without the mechanism inserted. This is because the plastic is too hard. At the point of realisation, I stopped my plans to use it and to have the key blade cut. The mini screwdriver and ring are of basic quality.
