Start with the same information
Use the year, make and model, and say whether you have a key that still starts the car. An all-keys-lost request is different from making a second working key. A remote that unlocks the doors but cannot start the vehicle should be described exactly that way.
Mention any changed locks, replacement ignition or other relevant history. If you have already purchased a fob, keep the part number and listing available. Appearance alone does not confirm that it can be made to work.
Separate the functions
Ask whether the quoted key will open the door, start the engine and operate the remote functions you need. Some fobs include an emergency blade; check whether cutting that blade is included.
A door-only spare may be a useful choice, but it should be a deliberate one. Don't assume a basic key price includes the electronics and programming of a complete remote key. Our replacement page explains how these parts fit together.
Add the visit and the conditions
Find out whether a visit charge is part of the estimate and what could change the total. Parts availability, the vehicle's condition and customer-supplied components can affect the proposed work. Get any revised scope explained before additional work is done.
Ask where the service can be performed and what proof of ownership or permission is required. If the documents are locked in the car, mention it in advance. Do not book a tow simply because you assume every lost-key job needs a dealership visit; first establish which options apply to the specific vehicle.
Finish with a function check
When the agreed work is complete, test the functions included in the price. Try the engine start, the relevant remote buttons and the emergency blade if it was supplied. Keep the spare separately from your usual key.
If the original key was lost, discuss what happens to its electronic access and to any mechanical lock it could still operate. These are related but separate questions. Car locksmith help covers the wider diagnosis when you are not yet sure a replacement is the right answer.
