Stolen car keys will only be covered by insurance if you have key cover—either included as standard or bought as an add-on extra. And even when theft of car keys is covered, check your policy's terms and conditions because you may need to prove that the person who stole your keys know the identity or location of your car for a car key cover claim to be accepted.
Lost car keys may be covered on your car insurance, but this varies from company to company. And just because you have key cover doesn't mean that you're covered for losing your keys—many policies only cover theft, not loss.
If your car key fob stops working—say if your fob will no longer lock and unlock the doors, open the tailgate or start the engine—then the fob might just need a new battery. Since car keys cost so much to replace, it's worth trying to replace the battery first. There are plenty of online tutorials showing how to replace a fob battery, and most simply require one or two 3-volt, lithium-ion coin batteries.
