Vector 3 Replacement Battery Covers

Did you try just changing the quantity to 2

Well I need 4 in total to cover 2 sets of dual sided pedals. The discount code is valid for 2 but doesn't work for 4.

Call Garmin support they just sent me another door for my single system.

Is this a second, or new, redisign after the initial replacements offered a few months after launch? 

Yes this is new design that has not be available before

Garmin recently became aware of issues with the battery contacts of returned Vector 3 units. It was determined that the swelling of batteries under normal discharge over time can cause the battery contacts to become compressed, which could result in power drops and spikes. This, combined with the shock and vibration experienced in cycling, could permanently deform the contacts leading to disconnects. The battery swelling does not present any safety–related concerns.

In an effort to improve the reliability and functionality of the Vector 3 system, we have redesigned the battery contacts and doors to prevent these issues from occurring. All Vector 3 owners can get free redesigned battery doors by entering the discount code below at Garmin.com.

Note: Vector 3 customers will need a quantity of two. Vector 3S will need a quantity of one.

i receive the doors tomorrow, as soon as i have them, i will post a photo here!

No they are a new design that have a raised center contact.
