Frequently asked questions

What is the DA2037KY isolator switch key for?

The DA2037KY is the removable operating key for a universal battery isolator, or cut-off, switch. Turning it through 90 degrees opens the switch to disconnect the battery from the vehicle's electrical circuit. The key then withdraws so the battery can't be reconnected without it.

Which isolator switch does the DA2037KY key fit?

The DA2037KY is the service replacement key for the DA2037 universal battery isolator switch. Order it to replace a lost or damaged original without buying a complete new switch. Check that your isolator is the DA2037 type, as keys aren't interchangeable between different isolator switch designs.

Can I buy the DA2037KY key on its own?

Yes, the DA2037KY is sold separately as a replacement key for the DA2037 isolator switch, so you don't need to replace the whole switch if you've lost the key. It restores secure battery isolation. It operates a common keyed isolator, so no programming is needed, just fit and turn.
