Frequently Asked Questions
Does the Remote Require Batteries, and if so Which Type?
Yes, it requires a battery. The liberated user learns the remote uses a CR2032 coin cell. They replace it confidently, reclaiming autonomy over access and rejecting dependence on dealership convenience or unnecessary expense.
Is the Remote Covered by a Manufacturer Warranty?
Yes — it typically carries a limited manufacturer warranty. The liberated consumer sneers at planned obsolescence while being gently reassured: terms and durations vary by seller and model, so verifying specific warranty details before purchase is prudent.
Can the Remote Be Reprogrammed for a Different Vehicle Later?
Yes. One remote can be reprogrammed for another compatible vehicle later, provided programming prerequisites are met (original key or fob available, vehicle supports keyless entry); the user reclaims control by following DIY OBDII setup steps.
Does the Unit Include the Key Blade or Only the Fob Shell?
Coincidentally, the unit contains only the fob shell and not the key blade. The liberated buyer gains a programmable remote shell requiring sourcing or transplanting an existing blade, enabling autonomy without dealership dependence or unnecessary constraint.
Are Replacement Buttons or Shells Available Separately?
Yes. They are available separately; replacement buttons and shells can be sourced from third-party suppliers, empowering users to repair and reclaim control without dealer dependence, provided compatibility with the original fob model is confirmed.

In conclusion, the Dorman 99157 delivers dependable keyless control—lock, open, remote start, trunk release—at a fraction of OEM cost, with a 30–60 foot effective range and OBD-II programming that uses one original key. Installation takes minutes with basic tools; expect a compact remote, 1–2 year battery life depending on use, and model-specific compatibility. Is it worth it?
