Programming for the Buick Regal Sportback in this period is an onboard smart-key learning process, not a traditional cut-and-program transponder routine. Sources describe using already-programmed smart keys and the vehicle’s learning mode to add additional smart proximity remotes, with the driver information display confirming when the new fob is accepted.
Common fob FCC IDs: HYQ4EA — check the back of your fob; we confirm the exact variant on site.

Year coverage comes from our consolidated vehicle programming dataset. Route-level programming status is reviewed against internal route sheets and available manufacturer, security-access, and professional tool references. Exact button sequences are marked source-verified only when we have year/equipment-specific support; where a year is labeled “route verified, steps vary,” we confirm the exact fob, trim, and prompts before programming.

Common questions
Does the Buick Regal Sportback use a regular metal key or a smart key?
It uses a smart/proximity key fob with an internal emergency blade key.
Can a replacement fob be programmed onboard?
Yes. Sources for the 2018 Regal describe onboard programming for additional smart keys when the vehicle is in learn mode.
Is HYQ4EA a confirmed FCC ID for this model?
Yes. A Regal TourX forum thread identifies FCC ID HYQ4EA for a compatible OEM key fob used with Regal TourX/Enclave; no better model-specific source was provided here.
Can you program a Regal Sportback key fob without going to the dealership?
For most years, yes - the route is onboard relearn or an OBD tool, both of which a mobile locksmith handles at your location.
Does this program the remote only, or the transponder key too?
It depends on your key type. Tell us your FCC ID and we will confirm.
What if my year says professional programming required?
Those years need a programmer or security access; we bring the tool to you and program it on site.
How much does it cost?
It depends on year, key type, and whether you have a working key. Call (833) 439-8636 for a firm price before we dispatch.
