The installation process is managed by Karshare. Either a team member will collect the key or you can post it securely to the Karshare installation team. This is used to build the keyless module.

Don’t worry if you don’t have a second key, we can help you source one from a reputable company – 40% of our owners to date have used this service.

We then arrange an installation date, which is the final step ahead of being shared.

We do not charge an upfront installation fee for the installation but take a 20% cut of your initial rental earnings until the balance has been paid. The total cost of the keyless technology is £195. A £105 charge applies when you de-install the technology from your vehicle if within the first 12 months.

Renting your car

Why share your car?

By renting out your car, you can help members of your community get to where they need to be. Car sharing also helps reduce CO2 emissions by decreasing the demand for more cars. With driver telematics to monitor all renter behaviour and contactless car collection, sharing your car has never been easier.

“To have an extra income revenue stream coming in via Karshare is absolutely brilliant. I certainly would recommend it.”

How does car sharing work?
Car sharing enables car owners to rent out their vehicles to drivers in the area. The entire renting process takes place through our mobile app. Owners have full control over when they want to share their car. Once a renter has selected a vehicle and verified their licence, they will pick up their car and start driving. The Karshare app will act as a virtual key to lock and unlock the vehicle, thanks to our KarshareGo technology.
How does insurance work?
When your car is rented, it is fully insured under Karshare’s comprehensive insurance policy, provided by QBE. Your own insurance is not affected. For more information on our policy, please click here.
Should your vehicle occur any damage during a rental, Karshare will immediately carry out an investigation and take care of organising any repair work required. If the damaged vehicle is undriveable and you don't have access to another car, a suitable courtesy car will be considered. We're unable to guarantee a specific make and model.
We ask that owners sharing their vehicle maintain a comprehensive insurance policy and up-to-date MOT on their vehicle at all times.
What happens if I receive a fine when I wasn’t driving?
If you receive notice of a fine (e.g. a speeding offence or parking ticket) and it occurred during a Karshare rental booking, please get in touch and we will ensure it is taken care of. You'll never be out of pocket for fines that occurred while you weren't the driver.
Do I have to keep my car clean and sanitised?
Karshare is committed to maintaining high cleaning and hygiene standards for the entire car sharing community. The very best sharing experience relies on each vehicle behind cleaned, sanitised and cleared of personal belongings by the car owner, and returned by renters in the same condition. Karshare will provide each car owner with a Covid-safe sanitisation kit which can be kept in the vehicle for use by both owner and renter.
How does fuel and mileage work?
Karshare operates a fair fuel policy to ensure that owners and renters are treated fairly. We record how much fuel is in the vehicle at the beginning and end of each rental. The renter is charged for any missing fuel if they do not return the vehicle at the same fuel level. If a renter returns the car with more fuel than they started with, we will refund them the difference. To ensure that there is enough fuel left for the next person, we ask renters that they do not return the car with less than a quarter of a tank.
All our vehicles have a daily mileage limit which is set by the owner. If a renter exceeds this limit, they will be charged an additional cost of £0.30 per mile, which is paid to the car owner via the rental earnings.
