Questions to Ask Your Tradie

• what type of lock do you recommend for this office door and why

• are you insured for commercial work and can you provide public liability and ID

• can you rekey or integrate with our masterkey system and what are the costs

• will the replacement meet our insurance and fire‑door requirements

• do you provide a written quote, timescale and warranty for parts and labour

• are there extra charges for out‑of‑hours work or for programming electronic locks

How to Avoid Surprises

• ensure a decision‑maker or keyholder is on site to approve lock type and keying

• check building access rules, reception procedures and any security passes required

• reserve parking or a loading bay near the entrance for the tradesperson

• confirm door handing, frame condition and whether the door is fire‑rated before work starts

• let the tradie know about masterkey systems or key code requirements in advance

• protect carpets and communal areas and advise tradesperson of any PPE or contamination rules
