Aftermarket Keyless Entry on Emira?

[crestima]

There are a few aftermarket Keyless Entry kits offered out there with proximity sensors to unlock doors. This continues to be a feature that I very much miss having on my Emira, and it's the only car in my household without it. Has anyone tried installing such a kit?

 

[Rapture]

I've been hoping they add this to an updated version on the Emira. I have to think the capability exists in the Emira's software. I miss this also. Maybe it then could be retrofitted easily (or not). It does explain why there is that rear hatch opening button front and (left) center on the dash.

Also wondering the same. Keyless entry is much needed.

I'd love to do the reverse - remove the electronic fob and have a metal key I can stick in and turn. I'm old, tho.

In the UK, Keyless entry is one of the primary methods Car thieves have been getting hold of high end cars.
Approaching a house late at night/early morning and having a receiver/transmitter they can get close enough to the key that people leave near the front of the house and then getting the car unlocked and drive away.
For me, the lack of Keyless Entry was a bonus.

This can defeated (as shown by Apple) by using high resolution timing to establish the travel distance of the signal, thereby only unlocking if the fob is actually near the car, not merely repeated at an abnormally long distance.

Thus, we can have keyless entry AND resistance to simple repeater attacks. It just requires doing the same thing Apple has already proven to work.

Not sure how they do that. The method in the UK is to have the Receiver near the door of the house and the transmitter next to the car. No idea if that overcomes the Apple solution or not, but its certainly what works over here currently, at least on most cars. JLR seem to be the worst for this, although that maybe down to the fact they also make the Cars that are in high demand

Do you have any links to aftermarket solutions?

My RS3 key had that high resolution timing feature and auto sleep after a few mins....

...so they broke into my house and stole the key instead

 

[crestima]

I didn't intend this thread to spark a debate of how secure or not a proximity keyless entry is. This inevitably becomes a risk/convenience tradeoff, not dissimilar to other everyday features like, for instance, garage door openers. Imo, there are two (or at least one) inherent theft deterrents for the Emira here in the States. It's a rare car, which makes it very noticeable and, for the manual versions, hardly any thief would even know how to drive one.

My Disco 5 insurance kept almost doubling every year due to the thefts. I tried to insure it in London one year and the quote was £8k with most refusing. Car was 3 years old at the time. Last year it went back for a security update and my insurance has now dropped from £1300 to £400, no other changes. Seems they overcame the most serious security hole(s)

100% agreed

Its done using "time of flight" measurement. Its fine to have a rx near the house and a tx next to the car, but time of flight reveals the distance is e.g. 60 feet instead of 10 feet, and the device rejects the attack.

These guys offer proximity keyless door lock kits ( https://vaistech.com/dealer-map/ ), but when I called them to inquire, they said that, because their installers don't have access to the CAN bus codes for the Emira (or any other Lotus model for that matter), they wouldn't be able to perform the installation.
