Combining 360 key and fob into 430 key

For years now I've wanted to stop having to carry key and fob around with me, thinking that the later 430 solution of having an all-in-one remote key would be so much neater.

A few years ago I looked at trying to cram the circuitry from the 360 fob into a 430 key but it was a non-starter.

I've recently been talking to a local micro-electronics specialist company who inform me that they've done stuff like this before and it really isn't that complicated to reverse engineer a 360 fob and then rebuild it onto a new PCB to fit the 430 remote key.

However.... the cost of doing this as a one off just for me is probative so I'm posting here to see if any other 360 owners (worldwide, they can deal with the 2 different frequencies) would be interested, basically the more interest, the lower the cost.

20 seems to be about the minimum which would run about $600 each plus the cost of the new remote key... take that to 40 users and the cost drops to around $300

The company are going to produce a proper costing for me early next week and confirm exactly what they'd need to make it work but just for some indicative interest I thought I'd post up here now.

No commitment, but would anyone else be interested?

 

I'm going to meet with the electronics chap next week and firm up from him exactly what he'll need.
As part of an earlier project to obtain spare keys, fobs and pin code I spent a lot of time researching how the 360 locking system works so have sent him all that knowledge, plus photos of the keys, fobs and internals for him to look at over the weekend.

If this looks like a go-er then I shall buy a 430 key and sacrifice one of my remotes for him to see what works.

My biggest concern is the rolling code aspect and how this will work with multiple owners and multiple remotes but he thinks that's not an issue.

I'll keep this thread updated, feel free to ask 360 owning friends / repost etc, as noted, the more owners, the cheaper it gets.

 

OK, will post more information on this thread once the electronics chap and I have conferred!

 

First two things I mentioned, the rolling code and the 2 different frequencies... I think they're getting a little fired up at the opportunity, they've asked me to go and meet with them later this week / early next.

 

So I have a face to face meeting with them on Thursday afternoon, watch this space.....

 

So by way of a little update.

I met with the electronics company and we talked through the way the system worked and the issues that they can foresee, we took apart one of my fobs and he analysed the components on the board and the power cell.

I have now ordered a 430 key shell whilst he is researching updated power sources, once my shell has arrived (scheduled for around 3 weeks time) we shall meet again and see if this project has legs!

 

Thank you for that info, I've passed it along to them just in case.
When I was there last week there was much examining of the internals of my fob under a microscope so they may already have the info as you say, but too much detail is far better than none at all.

 

I believe that the plan at the moment is to re-use the existing fob innards on a new circuit board shaped to fit inside the 430 key using a new, smaller style power source.

I shall know more detail after the next meeting, once they've had time to think it through fully.
